What is the volume of a sphere with a surface area of 25π yd2?

25 yards2 ????

If so....,

Area sphere = 4*pi*r2

You have area, so....,

25 yrd2 = 4*pi*r2

r = sqrt(25/4*pi)

= 1.41 yards in radius
-----------------------------

Volume sphere = 4/3*pi*r3

Volume = 4/3*pi(1.41 yrd)3

= 12 cubic yards
