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 formula to find the surface area of a sphere is given by:
Surface Area = 4πr^2
Given that the radius is 3.6 ft, we can substitute it into the formula:
Surface Area = 4 * 3.14 * (3.6)^2
Calculating the expression within parentheses first:
Surface Area = 4 * 3.14 * 12.96
Multiplying:
Surface Area = 162.24 * 3.14
Surface Area ≈ 509.04 ft^2
Rounded to the nearest hundredth, the surface area of the sphere is approximately 509.04 square feet.
