|---|---|---|---|
1 |
Problem |
The volume of a cone is 942 cubic inches and the radius is 10 inches, find the height of the cone. |
|
2 |
Step |
The given volume and radius of cone are |
v = \$942 "inch"^3\$ r = 10 inches |
3 |
Formula |
The volume of cone is |
v = \$ π times r^2 times h/3\$ |
4 |
Step |
Substitute the values in the formula |
942 = \$π times 10^2 times h/3\$ 942 = \$314 times h/3\$ 942 = \$314/3 times h\$ |
5 |
Step |
Move h coefficient to left hand side,we get |
\$947/104.66\$ = h |
6 |
Step |
After simplication |
h = 9 |
7 |
Step |
The height of a cone is 9 inches. |
