Question

if diameter is 12 inches, what is the area

Answer 1

The formula to calculate the area of a circle is A = πr^2, where r is the radius of the circle. Since the diameter of a circle is equal to 2 times the radius, we can determine the radius by dividing the diameter by 2:

r = 12 inches / 2 = 6 inches

Now we can calculate the area:

A = π(6 inches)² = π(36 square inches) ≈ 113.10 square inches

Therefore, the area of the circle with a diameter of 12 inches is approximately 113.10 square inches.
