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:
D.) 400π
Step-by-step 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.
