If the volume of a sphere inscribed in a cubic box is 36pi, find the surface area of the box

Answers

Answer:

Surface area of the cube = 216 square units

Step-by-step explanation:

Let the length of a side of a cube = x unit

Diameter of the sphere inscribed in this cube = length of a side of the cube

Volume of the sphere = [tex]\frac{4}{3}\pi r^{3}[/tex]

Where r = radius of the sphere = [tex]\frac{x}{2}[/tex] units

36π = [tex]\frac{4}{3}\pi (\frac{x}{2})^{3}[/tex]

36π = [tex]\frac{4x^{3}\pi }{24}[/tex]

36×24 = 4x³

x = [tex]\sqrt[3]{\frac{36\times 24}{4} }[/tex]

x = 6 units

Length of a side of the cube = 6 units

Surface area of the cube = 6×(Side)²

                                          = 6×(6)²

                                          = 216

                                          = 216 square units

Mindy, a local artist, sells a piece of art at the pizza shop for $15, and the shop takes 15 percent commission. Instead of receiving money, Mindy would like a $12 pizza, including 5 percent sales tax. Is this a fair trade? Explain how to find the solution. Please answer quickly!! I have seen many other answers to this question, however, I don't see anybody who answered the sales tax. What does the sales tax mean??? Do you add it to the $12 pizza???
ASAP PLEASE!!!

Answers

OK so basically, she’s at the pizza shop selling paintings, since she’s selling it at their venue, the owners may demand a small commission of a price. In this case that is 15% of $15. 15% of 15 is 2.25, meaning she only gets $12.75. Mindy would like to buy a pizza for $12, she has 12, but does she have enough to make the sales tax. 12×.05 is $0.6 dollars which means she has enough money to buy it.
Yes the Sales Tax should be added onto the total cost considering you always pay tax with whatever you buy! If the pizza is 12$ the sales tax would be 0.60$ which makes the total for a pizza 12.60$.
Now if the 15% commission was it, it would be 2.25$, leaving 12.75$ after.

So it wasn’t multiple choice, but if mindy gets a pizza, that’d be losing 0.15$ each time instead of paying commission

Side A: 14

Side B: 12

Side C: 11.2 or 11 if you round to the nearest whole number.

Step-by-step explanation:

Angle A;

Since we know angles B and C we can use those to help us find angle since all three angles should add up to 180°.

90-50=40

Angle A= 40°

Side C;

Since we know all the angles now and the other two side lengths, we will use those to help us find Side C.

cos 40°= C/14

C/14= cos 40°

C/14=  .8

C= .8 x 14

C= 11.2

The volume of a solid cylinder is 1584 cubic cm and its height is 14 cm. The radius is

Answers

Answer: 6 cm

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:  

Volume of a cylinder (V): π x radius ² x height  

Replacing with the values given and solving for v (Volume)  

1584 = π x r ² x 14

Solving for r:

1584 / (π x 14) = r²

36.01 = r²

√36.01 = r

6 cm = r

In conclusion, the radius of the cylinder is 6 centimeters.

Feel free to ask for more if needed or if you did not understand something.

Answer:

The radius is 6 cm

Step-by-step explanation:

To solve this, we will follow the steps below:

write down the formula for finding the volume of a cylinder

volume of a cylinder =πr²h

from the question volume of the cylinder = 1584 cm²

height = 14 cm

substitute the formula and solve for r

π is a constant and is ≈ 3.14

1584 = 3.14×r²×14

1584= 43.96 r²

divide both-side of the equation by 43.96

36≈ r²

take the square root of both-side

√36 = √r²

6 = r

r = 6cm

The radius is 6 cm

Linda is building steps for her porch. What is the volume of the steps?
144,000 cm3
288,000 cm3
324,000 cm3
540,000 cm3

Answers

Answer:

The volume of the steps is:

324,000 cm3

Step-by-step explanation:

Remember that the volume regularly is:

Volume = height * width * depth.

There are many forms to solve this exercise, but I'll show you two:

1. Imagine that aren't steps but a big solid, then its volume would be:

Volume of big solid = 60 cm * 60 cm * 120 cm Volume of big solid = 432000 cm3

Now you can subtract the volume of a small solid with measures 30 cm * 30 cm * 120 cm (where is the blank for the step):

Volume of a small solid = 30 cm * 30 cm * 120 cm Volume of a small solid = 108000 cm3

Now you subtract:

Volume of the building steps = 432000 cm3 - 108000 cm3 Volume of the building steps = 324000 cm3

2. The building steps are formed by three solid with volume 30 cm * 30 cm * 120 cm, so:

Volume of the building steps = 3 (30 cm * 30 cm * 120 cm) Volume of the building steps = 324000 cm3

5.4x = 2.6* 6.21

In 2005 a house was purchased for $280,000 and
in 2013 it was sold at $334,000. Assuming that
the value of the house increased at a constant
annual rate what will be the price of the house in
the year 2018?

Answers

Given that in 2005 a house was purchases for 280,000 and was later sold in 2013 for 334,000, determine the increase value of the house and what the price of the house will be in 2018.

First, we subtract the two values of the house on both dates.

334,000 - 280,000 = 54,000

Then, divide the difference by the amount of years from 2005 to 2013.

54,000/8 = 6,750

Since, it says the value increases at a constant rate, this indicates that it is a linear function.

So, the linear function would start at 280,000 as the y-intercept and the slope is 6,750.

Linear Function: y = 6750x + 280,000

Lastly, to find the price of the house in 2018, we just need to plug in 13 for x since x represents the years.

y = 6750x + 280,000

Plug in 13 for x.

y = 6750(13) + 280,000

y = 87750 + 280,000

y = 367,750

Thus, the value of the house in 2018 is $367,750.

At the beginning of the month, a rain barrel contained 12 ounces of water. At the end of the month there are 8 1/4 cups of water in the rain barrel.


How many cups of rain water were added to the barrel during the month?

Answers

Answer:

The cups of rain water that were added to the barrel during the month is:

6.75 cups.

Step-by-step explanation:

First, you must know the conversion units between ounces and cups:

1 cup = 8 ounces.

Then, at the beginning of the month, the rain barrel contained 12 ounces, what is in cups:

1 cup = 8 ounces. X = 12 onces.

We operate:

X = (12 * 1) / 8 X = 1.5 cups

Now, how at the end of the month there are 8 1/4 cups of water in the rain barrel, in a decimal number it is equal to:

8 1/4 cups = 8.25 cups

To know what is the cups of rainwater were added to the barrel during the month, you must subtract the number of cups at the beginning of the month to the number of cups at the end of the month:

Cups of rainwater that were added = 8.25 cups - 1.5 cups Cups of rainwater that were added = 6.75 cups.

6.75
