The SA of a sphere is 4 times the area of the base of if you cut it in half. So that would mean that that would be (9/4)pi yd2. Pi*r^2=area of a circle, so that means the radius is 3/2 yds.
The volume of a sphere is (4/3)*pi*r^3. If we plug in the radius, we get:
(4/3)*pi*(3/2)^3
(4/3)*pi*(27/8)
(27/6)pi, or 4 and 1/2 pi
If you want an actual number with pi used, you get about 14.137166952
