Question

Use the formula V=pier ^2

to find the height of a cylinder when the radius is 3
inches and the volume is 127.23 cubic inches.


A)13.5inches


B)115.1inches


C)4.5inches


D)6.4inches

Answer 1

Explanation:

volume of cylinder = πr²h

πr²h = 127.23 cubic inches

3.14 * 3 * 3 * h = 127.23

h = 127.23 / 3*3*3.14

=127.23 * 100 /3*3*3.14*100

=12723/ 3*3*314

= 4241 / 3*314

=4241/ 942

=4.502 inches

h = 4.5 inches
