Question

A cone shaped paperweight has the diameter of 3 inches and a height of 5 inches what is the volume of the paperweight using 3.14 for pi (answer using decimal)

Answer 1

v = 11.775

The volume of a cone is v = π r^2 h/3

r: d/2 --> 3/2 --> 1.5

h: 5

v = π 1.5^2 5/3

v = π (2.25) (1.67)

v = π (3.75)

v = 11.775

And there you have it! The volume of the paper weight is 11.775.

Hope this helps!
