What is the volume of a sphere whose surface area is 100π square units?
A

(100/3)π cubic units or units3

B

(500/3)π units3

C

160π units3

D

(375/4)π units3

E

520 units3

参考答案

参考解析
解析：
The formula for the surface area of a sphere is SA = 4πr2. 100π= 4πr2, 25 = r2, 5=r. The volume is, therefore, (4/3) πr3 = 4/3π(5)3=(4/3)π(125) =(500/3)π
