Question

find the volume of sphere whose surface are is 55.44​

Answer 1

Explanation:

$let \: r \: be \: the \: radius \: of \: the \: sphere$

$given \: surface \: area \: of \: the \: sphere$

$= 55.44$

$= 4\pi \: {r}^{2} = 55.44$

$= {r}^{2} = 55.44 \div (4 \times \frac{22}{7} )$

$= {r}^{2} =( 55.44 \times 7) \div (4 \times 22)$

${r}^{2} = 4.41$

$r = \sqrt{4.41}$

$r = 2.1$

$now$

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

$\frac{4}{3} \times \frac{22}{7} \times 2.1 {}^{3}$

$\frac{4}{3} \times 22 \times 0.3 \times 2.1 \times 2.1$

$4 \times 22 \times 2.1 \times 2.1 \times 0.1$

$38.808 \: cm {}^{3}$
