Question

the surface area of a sphere is 10182/7 sq.cm. what is it's volume​

Answer 1

practice and solve yourself

Answer 2

surface area of sphere = 1018 2/7 cm2

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

= 4*22/7r2 =7128/7

=88/7r2 = 7128/7

r2= ( 7128/7 )*(7*88 )

r2 =7128/88

r2= 81

Taking square root on both side

r = 9

Volume of sphere =

$4 \div 3\pi {r}^{3}$

4/3*22/7* 93

88/21*729

64152/21=3054.9 cm2
