Question

Find the volume of sphere if its surface area is 514 square cm.​

Answer 1

Answer:

V

≈

1095.77

A

Surface area

Answer 2

Answer:

33510 cm^3

Step-by-step explanation:

surface area = 4πr^2 = 514 cm^2

r^2 = 514/4π

r^2 = 403 ( approx.)

r = 20 cm ( approx. )

now volume of sphere = 4/3 πr^3

= 4/3 * 22/7 * 20* 20*20

= 33510 cm^3
