Answer 1

Hello friend

____________________________


Given :

Volume of a sphere = 113040 cu.cm


We have to find it's Radius (r) = ??


We know that,

Volume of sphere =
$\frac{4}{3} \pi \: r {}^{3}$

$113040 = \frac{4}{3} \times 3.14 \times r {}^{3} \\ \\ \frac{113040 \times 3}{4 \times 3.14} = r {}^{3} \\ \\ \frac{28260 \times 3}{3.14} = r {}^{3} \\ \\ 9000 \times 3 = r {}^{3} \\ \\ r {}^{3} = 27000 \\ \\ r = 30 \\ \\ r = 30 \: cm$

Therefore, the radius of sphere is 30cm.


I hope this will help you...


Thanks.........
