The formula to calculate the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the radius is 15 inches, plugging it into the formula:
A = 3.14 * 15^2
A = 3.14 * 225
A ≈ 706.5
Therefore, the area of the circle is approximately 706.5 square inches.
To find the area of a circle, we use the formula A = πr^2, where A represents the area and r represents the radius.
Given that the radius (r) is 15 inches, we can substitute this value into the formula:
A = 3.14 * (15^2)
Calculating this gives:
A = 3.14 * 225
A = 706.5 square inches.
Therefore, the area of the circle with a radius of 15 inches is approximately 706.5 square inches.
