Find The Exact (leave Pi) And The Approximate ( Pi = 3.14 ) Circumference For Each Circle(#s A-F ONLY)

Answers

Answer 1

Answer/Step-by-step explanation:

a. Circumference (C) = πd

d = 12 cm

π = 3.14

Exact value of C = π*12 = 12π cm

Approximate value of C = 12*3.14 = 37.68 cm

b. Circumference (C) = πd

d = 8 m

π = 3.14

Exact value of C = π*8 = 8π m

Approximate value of C = 8*3.14 = 25.12 m

c. Circumference (C) = πd

d = 6 km

π = 3.14

Exact value of C = π*6 = 6π km

Approximate value of C = 6*3.14 = 18.84 km

d. Circumference = πd

d = 9 ft

π = 22/7

Exact value of C = π*9 = 9π ft

Approximate value of C = 9*22/7 = 28.2857143 ≈ 28.29 ft (nearest hundredth)

e. Circumference = 2πr

r = 4 mm

π = 22/7

Exact value of C = 2*π*4 = 8π mm

Approximate value of C = 2*22/7*4 = 25.1428571 ≈ 25.14 mm (nearest hundredth)

f. Circumference = 2πr

r = 7 mi

π = 22/7

Exact value of C = 2*π*7 = 14π mi

Approximate value of C = 2*22/7*7 = 44 mi (nearest hundredth)

What is the distance between (1,7) and (9,1)

Answers

Answer:

10

Step-by-step explanation:

Given two points we can use the distance formula to calculate the distance between the two points.

Formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Where the x and y values are derived from the given points.

we are given the points (1,7) and (9,1)

To find the distance we plug in the x and y values of the points into the formula

[tex]d=\sqrt{(9-1)^2+(1-7)^2} \\9-1=8\\1-7=-6\\d=\sqrt{8^2+(-6)^2} \\8^2=64\\-6^2=36\\d=\sqrt{64+36} \\64+36=100\\\sqrt{100} =10\\d=10[/tex]

So we can conclude that the distance between the points (1,7) and (9,1) is 10 units

Step-by-step explanation:

Given that :

A circle has a radius of 5 centimeters.

to find :

What is its area?

formulas used :

A = πr²

where,

A = areaπ = 22/7 r = radius

explanation :

finding the area of circle

⟼ A = πr²

⟼ A = 22/7 × 5²

⟼ A = 22/7 × 5 × 5

⟼ A = 3•14 × 5 × 5

⟼ A = 3•14 × 25

⟼ A = 78•5

the area of circle is 78•5 centimeters

the area is 78.5 cm because the formula is A=3.14r^2 or area=3.14•5^2

Step-by-step explanation:

The only options that are equal to 1 ton 200 pounds are C and E.

What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We are given that;

1 ton 200 pounds.

Now,

We can compare this value with the given options and see which ones are equal to it. We can use the conversion factors from the search results34 to convert ounces to pounds. We get:

A. 35,000 ounces = 35,000 / 16 pounds 35,000 ounces = 2,187.5 pounds This is not equal to 2,200 pounds.

B. 1,200 pounds = 1,200 pounds This is not equal to 2,200 pounds.

C. 2,200 pounds = 2,200 pounds This is equal to 2,200 pounds.

D. 1,200 pounds 100 ounces = (1,200 + (100 / 16)) pounds 1,200 pounds 100 ounces = (1,200 + 6.25) pounds 1,200 pounds 100 ounces = 1,206.25 pounds This is not equal to 2,200 pounds.

E. 1 ton 100 pounds 1,600 ounces = ((1 x 2,000) + (100 + (1,600 / 16))) pounds 1 ton 100 pounds 1,600 ounces = (2,000 + (100 + 100)) pounds 1 ton 100 pounds 1,600 ounces = (2,000 + 200) pounds 1 ton 100 pounds 1,600 ounces = 2,200 pounds This is equal to 2,200 pounds.

Therefore, by the conversion the answer will be 1 ton 200 pounds are C and E.

Answer:

b=18.76

Step-by-step explanation:

Let the line that splits the big triangle into two small triangles be x.

Let the unmarked side of the big triangle be y.

Consider the big triangle. By Pythagorus:

(6+16)²=b²+y²

484=b²+y²

y²=484-b²

Consider the small left triangle. By Pythagorus:

y²=6²+x²

y²=36+x²

x²=y²-36

Consider the small right triangle. By Pythagorus:

b²=16²+x²

b²=256+x²

b²=256+x²

b²=256+y²-36

b²=220+y²

b²=220+484-b²

2b²=704

b²=352

b=18.7616630393

b=18.76

What is the result of subtracting the second equation from the first?
-4x-2y=-2
x-2y=9

Answers

Answer:

Given:

-4x - 2y = -2   x - 2y = 9

Subtracting:

-4x - 2y - (x - 2y) = -2 - 9-4x - 2y - x + 2y = - 11-5x = -115x = 11x = 11/5x = 2.2

You can now find y:

2.2 - 2y = 92y = 2.2 - 92y = - 6.8y = -6.8/2y = -3.4

Find the measure of A as indicates in the picture.
In case the picture blurs
Top angle = x + 63
Left angle = x + 96
Right angle = x + 149

Answers

Answer:

m∠A = 58°

Step-by-step explanation:

In ΔABC,

m∠BAC = (x + 63)°

m∠ABC = (x + 96)° [Vertically opposite angles]

m∠ACB = (180° - 149°)

             = 31°

By triangle sum theorem,

m∠ABC + m∠ACB + m∠BAC = 180°

(x + 96) + 31 + (x + 63) = 180°

2x + 190 = 180

2x = -10

x = -5

Therefore, measure angle A = (x + 63)

                                               = -5 + 63

                                               = 58°

Answer:

(i) 22.5

(ii) 7.2

Step-by-step explanation:

(i)

AB:PQ = 2:5 = 1:2.5

So PQ is 2.5 times longer than AB.

PQ=2.5AB=(2.5)9=22.5

(ii):

Since the triangles are similar, their sides are in ratio to each other. So if PQ was 2.5 times longer than AB, QR must also be 2.5 times longer than BC:

QR=2.5BC

BC=QR/2.5=18/2.5=7.2
