square inches

1 answer

The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius. In this case, the diameter is given as 10 inches. Since the radius is half the diameter, the radius would be 5 inches.

Using the formula, we can calculate the area:
A = πr^2
A = 3.14 * 5^2
A = 3.14 * 25
A = 78.5

Therefore, the area of a circle with a diameter of 10 inches is 78.5 square inches.
