# Find what is the Volume of Hemisphere for Radius is 15

## Work with Steps to find Volume & Surface Area of Hemisphere for r=15

__Question:__

Find what is the volume & surface area of hemisphere whose radius is 15 inches?

__Workout :__

step 1 Address the formula, input parmaeters & values

Radius = 15 in

step 2 Apply radius values in Volume formula

Volume V = 2πr³/3

= 2 x 3.1416 x (15)³/3in³

= 2 x 3.1416 x 3375/3in³

= 21206/3in³

Volume V = 7068.5835 in³

step 3 Find Surface area using below surface area formula

Surface Area = 2πr²

= 2 x 3.1416 x (15)² in²

= 2 x 3.1416 x 225 in²

Surface Area = 1413.7167 in²
