Question

Moe painted the lid of the barrel. The circumference of the lid is 32π inches. What is the area of the lid in square inches?

Answer 1

A ≈ 81.487 in²

Explanation:

You know that circumference is C = 2πr, where r is the radius.

So,

C = 2πr

32 = 2(3.14)r

r ≈ 5.093 in

We also know that the formula for the area of a circle is A = πr², so:

A = πr²

A = (3.14)(5.093)²

A ≈ 81.487 in²
