Question

Find the area.
20 cm

Answer 1

1256.64
`cm^(2)`

Explanation:

The formula for the area of a circle is A=
`\pi r^(2)`

A=
`\pi 20^(2)`

A equals approximately 1256.64
`cm^(2)`

Answer 2

Answer: About 1,256.64 cm²

Explanation:

We will use the formula for the area for a circle, substitute known values, and solve. Below, r is equal to radius. The radius is half of the diameter or half of a circle's width. Here, r = 20.

A = πr²

A = π(20 cm)²

A ≈ 1,256.64 cm²
