Given:
For cylinder P: radius = 4.25 in. and height = 14 in.
For cylinder Q: radius = 7 in. and height = 8.5 in.
To find:
The volume of each cylinder.
Solution:
Volume of a cylinder is

where, r is radius and h is height. Use 3.14 for  .
.
Using the above formula, the volume of cylinder P is



Using the above formula, the volume of cylinder Q is


Therefore, the volume of cylinder P is 794.03 sq. in. and volume of cylinder Q is 1307 sq. in.
