Question

Find the surface area of a sphere with a radius of 3.6 ft. Use 3.14 for pi. Round your answer to the nearest hundredth, if necessary the surface area is ft.2

Answer 1

The formula for the surface area of a sphere is A = 4πr^2.

Plugging in the given radius, we have A = 4 * 3.14 * 3.6^2.

Calculating the expression inside the parentheses first, 3.6^2 = 12.96.

Multiplying 12.96 by 4, we get 51.84.

Therefore, the surface area of the sphere is 51.84 square feet.
