12. Find the height of the cone shown below if the volume is 3.6 cubic inches. Round your answer to the nearest tenth.

Answers

Answer:

h = 1.34 inches

Step-by-step explanation:

Given that,

The volume of cone, V = 3.6 cubic inches

Let the radius of cone is, r = 1.6 inches

We need to find the height of the cone. The formula for the volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h\\\\h=\dfrac{3V}{\pi r^2}\\\\h=\dfrac{3\times 3.6}{\pi \times 1.6^2}[/tex]

h = 1.34 inches

So, the height of the cone is equal to 1.34 inches.

A rectangle has perimeter 20 m . Express the area of the rectangle as a function of the length of ones its side.

Answers

Answer:

A = 10W - W²

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

Area of a rectangle =LW

L is the length

W is the width

Given

Perimeter = 20m

20 = 2 (L+W)

10 = L+W

L = 10 - W ....2

Substitute equation 2 into the formula for calculating the area

Recall that A = LW

A = (10-W)W

A = 10W - W²

Hence the area of the rectangle as a function of the length of ones its side is expressed as A = 10W - W²

find 0. round to the nearest degree. 15 4

Answers

Answer:

68.2

Step-by-step explanation:

You can use a^2+b^2=c^2 to find the length of the missing side, where c^2 is the hypotenuse (side 14).

5^2+x^2=14^2

25+x^2=196

x^2=196-25=171

x=13.0 (rounded)

Next, use one of sin or tan to find the missing angle.

Sin0=opposite/hypotenuse

Sin0=13/14

0=sin^-1(13/14)

0=68.213 (rounded)

The value of the angle asked is 69°.

Given is a right triangle, with base = 5 units and the hypotenuse is 14 units,

We need to find the angle θ which is between the base and the hypotenuse,

To find the angle θ between the base and the hypotenuse of a right triangle, we can use the trigonometric function cosine (cos).

The cosine of an angle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse.

In this case, the base of the triangle is the adjacent side, and the hypotenuse is given as 14 units.

Therefore, we can use the following formula:

cos(θ) = adjacent/hypotenuse

Plugging in the values we know:

cos(θ) = 5/14

To find the angle θ, we need to take the inverse cosine (arccos) of both sides:

θ = arccos(5/14)

θ = 69°

Hence the value of the angle asked is 69°.

APR of 0.995%. How much money would a $1000 investment be worth at the end of 5 years

Answers

Answer:

The amount in 5 years will be $1,050.75

Step-by-step explanation:

Here, we want to calculate the worth of the given amount of money in the next 5 years

We use the compound interest formula here;

A = P(1 + r/n)^nt

A is the amount after the given number of years

P is the amount invested which is $1,000

r is the rate which is 0.995% which is 0.995/100 = 0.00995

n is the number of times per year interest is compounded and that is 1

t is the number of years which is 5

substituting these values, we have

A = 1000( 1 + 0.00995/1)^5

A = 1000(1.00995)^5

A = $1,050.75

The diameter of a circle is 14 ft. Find its area to the nearest tenth.

Answers

Answer:

The answer is 153.9

Step-by-step explanation:

To get the answer we will first divide 14 by 2 because we are trying to find the area.  14 ÷ 2 = 7.  Now multiply 7 x 7 x π, which equals 154.9 rounded to the nearest tenth.

Answer:

153.9 ft.²

Step-by-step explanation:

[tex]A=\pi r^2[/tex] where r is the radius of the circle

The radius is equal to half the diameter, so to find r, divide 14 ft. by 2:

14÷2=7

Plug 7 into the equation as r

[tex]A=\pi (7)^2\\A=\pi (49)\\A=153.9[/tex]

Therefore, the area of the circle is 153.9 ft.² when rounded to the nearest tenth.
