Question

Gunther drew a circle. The radius of the circle is 20 inches. He uses the formula below to determine the area of his circle

Answer 1

D.) 400π

Explanation:

The formula for the area of a circle is:

A = πr²

Substitute the radius into the equation:

A = πr²

A = π(20²)

Solve:

A = π(20²)

A = 400π

Therefore, the area of the circle is 400π square inches.
