Question

The Smith family has a circular shaped pool with a radius of 10 feet. What is the minimum amount of material needed to make a cover for the surface of the pool?

62.8 sq. feet

314 sq. feet

31.4 sq. feet

100 sq. feet

Answer 1

A

Explanation:

A circular shaped pool.

The radius is 10 feet.

We need to find the surface area to make a cover for the pool.

We can use the formula for the area of a circle:

A =
`\pi`r²

A = (3.14)(10)(2)

A = (31.4)(2)

A = 62.8

The minimum amount of material needed to make a cover is 62.8 square feet.

hope this helps :)

Answer 2

314 sq. feet

Explanation:
The surface area of the pool would be the area in math. The equation for solving the area of a circle goes as follows:

A=πr^2
π·10^2
314
