A spherical container is designed to hold as 132 volume. Its radius is 3.2 in. Find the surface area of the sphere rounded to the nearest square inch.

Answer 1

The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere.

Given that the radius of the sphere is 3.2 in, we can plug this into the formula to find the surface area:

Surface area = 4π(3.2)^2
Surface area = 4π(10.24)
Surface area ≈ 40.7 in^2

Rounded to the nearest square inch, the surface area of the sphere is 41 in^2.
