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.(1 point)
The surface area is ft^.2

Answer 1

To find the surface area of a sphere, we use the formula:

Surface area = 4πr^2

Given that the radius is 3.6 ft, we can substitute this value into the formula:

Surface area = 4 * 3.14 * (3.6)^2
Surface area = 4 * 3.14 * 12.96
Surface area = 51.84 * 3.14
Surface area ≈ 162.46 ft^2

Therefore, the surface area of the sphere is approximately 162.46 ft^2.
