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 for the surface area of a sphere is given by:
Surface Area = 4πr²,
where r is the radius of the sphere.
Substituting the given radius of 3.6 ft and using the approximation π ≈ 3.14, we can calculate:
Surface Area = 4 * 3.14 * (3.6)²
Surface Area ≈ 4 * 3.14 * 12.96
Surface Area ≈ 162.24 ft²
Therefore, the surface area of the sphere, rounded to the nearest hundredth, is approximately 162.24 ft².
