Question

Find the surface area and volume of a sphere whose radius is: (1) 35 cm​

Answer 1

Answer:

$We \: \: know,  \\ Surface \: \: area \: \: of \: \: the \: \: sphere \: \: is \: \: equal \: \: to \: \:  4πr2 \\  So, A=4πr2 \\ =4×722×35×35 \\ =15400 cm2$

$Volume \: of \: sphere =34πr^{3} \\ =34×722×35×35×35 \\ =1,052,495,500 cm3$
