Question

Find the volume of a sphere whose surface area is 154 cm?
hemisphere. ​

Answer 1

Answer:

V = 4/3 ( πr^3)

S A= 4πr^2

Step-by-step explanation:

In a given que

S. A of sphere = 154 cm^2

4πr^2. = 154

πr^2 = 154/4

πr^2= 38.5

r^2 = 38.5÷3.14 { π = 3.14 }

r^2 = 122 cm

r = 11.1 cm

Volume of sphere= 4/3( πr^3)

=> 4/3×22/7×11.1×11.1×11.1

=> 1.3×3.14×11.1×11.1×11.1

=>. 5582 cm^3
