Question

find the volume of sphere of radius 6.3 CM if the formula is 4/3×22/7×rcube

Answer 1

Here is the answer

Given :-
r = 6.3 cm

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

To find :-

Volume of sphere = ?

Solution:-

Volume of sphere =
$\frac{4}{3} \times \frac{22}{7} \times 6.3 {}^{3}$


$\frac{4}{3} \times \frac{22}{7} \times 6.3 \times 6.3 \times 6.3$


$\frac{4}{3} \times 22 \times 0.9 \times 6.3 \times 6.3$


$4 \times 22 \times 0.3 \times 6.3 \times 6.3$


$88 \times 0.3 \times 6.3 \times 6.3$


$26.4 \times 6.3 \times 6.3 \\ \\ = 166.32 \times 6.3 \\ \\ = 1047.816$


$= \bf{1047.8 \: cm {}^{3}}$

Volume of the sphere is 1047.8 cu. cm.
