解

S u r f a ce a re a o f a s p h ere i s 254.5 in c h e s^{2} . Wha t i s t h e r a d i u s in d ec ima l f or m

r a d i u s : \frac{s ^{2} in c h e}{2 π}

解答ステップ

Given:

s u r f a ce a re a : in c h e s^{2}

指定された球体の半径

S u r f a ce A re a = in c h e s^{2} : r = \frac{s ^{2} in c h e}{2 π}

r a d i u s : \frac{s ^{2} in c h e}{2 π}
