Question

If the radius of sphere is 7m. calculate volume of sphere​

Answer 1

Answer:

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

$= \frac{4}{3} \times 7 \times 7 \times 7 \\ = \frac{1372}{3}$

= 457.3 m^3 (approx)

which is the required ans

Answer 2

Answer:

$\frac{4}{3} \pi {r}^{3} = \frac{4}{3} \times \frac{22}{7} \times {7}^{3} \\ = \frac{4312}{3} \\ = 1437.33 \: {m}^{3}$
