Question

Find the volume of a sphere with a surface area of 1296π in^2

Answer 1

Surface area of a sphere is 4pir^2. So, divide by 4pi: r^2 = 324, and r=18. Now plug that back in to volume formula, (4/3)*pi*r^3, and you'll get 7776pi.

Answer 2

A=4πr^2
solve for r
1296π=4πr^2
324=r^2
r=18
V=4/3πr^3
V=4/3π(18^3)
V=7776π in^3
