Question

a circular stage has a radius of 8ft.Flynn wants to paint a red line along the edge of the stage. He calculates its approximate circumference this way: 3.14(8)(8)= 3.14(64) = 200.96.(A) What error did he make in his calculation?(B)Flynn also wants to paint the the stage floor.One Quart of paint covers 75 square feet of space.What is the fewest quarts of pain Flynn will need?

Answer 1

Step-by-step explanation:

Circumference = 50.27ft

He used the formula for the area of a circle which is

B.

A = 201.06ft^2

201.06/75 = 2.68

He will need 3 quarts of paint.

Answer 2

C=

`2 * \pi * r`
Circumference = 50.27ft

He used the formula for the area of a circle which is

`\pi * r^(2)`
B.
A = 201.06ft^2

201.06/75 = 2.68
He will need 3 quarts of paint.
