Question

Explain it step by step ​

Answer 1

Step-by-step explanation:

Surface area of sphere = 4πr square= 154cm square

=> 4×22/7r square = 154cm square

=> r square = 154/4 × 7/22

=> r square = 49/4

=> r = √49/√4

•

• • r = 7/2 = 3.5cm

Volume of the sphere = 4/3πr cube

= 4/3× 22/7× 3.5 cube

= 88/21 × 42.875 =179.67 cm cube

There for the volume of of sphere is 179.67cm cube
