A sphere has a volume of 900 cubic inches. Find its surface area to the nearest whole number. I know how to solve it, but I can't figure out how to punch it into my calculator. I have searched it and watched videos and its not working. Please Help!!!

The volume of the sphere is calculated using the equation V = 4nr3/3Substituting, 900 in3 = 4nr3/3 ; r = 5.99 inThen, solve for the area of the surface of the sphere using the equation SA = 4nr2 SA = 4π(5.99)2 = 450.80 in2Thus, in the nearest whole number, SA was calculated to be almost 451 in2.
