The volume of a sphere is 2930pi cubic centimeters. What is the 半径 of the sphere? Round to the nearest whole number.

解

T h e v o l u m e o f a s p h ere i s 2930 π c u bi c ce n t im e t ers . Wha t i s t h e r a d i u s o f t h e s p h ere ? R o u n d t o t h e n e a res t w h o l e n u mb er .

r a d i u s : 13 c m

解答ステップ

Given:

v o l u m e : 2930 π c m^{3}

指定された球体の半径

V o l u m e = 2930 π : r = 3 \frac{4395}{2}

r a d i u s : 3 \frac{4395}{2} c m

3 \frac{4395}{2}

を最も近い整数に四捨五入する:

13

r a d i u s : 13 c m
