Question

792/7=4/3π r^3, find the value of r​

Answer 1

$\huge \mathscr{\orange {\underline{\pink{\underline {★Answer★:-}}}}}$

volume of sphere is 4πr³/34πr³/3

TSA of sphere 4πr²4πr²

TSA =792/7

4πr²=792/7

here we have to find radius

r=√729/√7×π×4

r=√729/√28π

r =27/√28

r=16.03

Now finding volume by formula

4πr³/3

we get ,

4π(16.03)³/3

= 17253.98 m³

Answer 2

Answer:

792/7 = (4/3)πr³

or, 198/7 = (1/3)πr³

or, 594 = 7×(22/7)r³

or, r³ = 594/22

or, r³ = 27

or, r = 3
