1 |
Problem |
Find the radius of a cone whose volume and height are 225 cubic units and 16 units respectively. |
|
2 |
Step |
The given values are |
V = 225 and h = 16 |
3 |
Formula: |
The volume of cone is |
\$ V=1/3 π r^2 h\$ |
4 |
Step |
Now substitute the values |
\$225 = 1/3 π r^2 times 16\$ |
5 |
Step |
After simplification |
\$225 = 16.74 r^2\$ |
6 |
Step |
After simplification |
\$r^2 = 13.44\$ |
7 |
Step |
After simplification |
\$r = \sqrt13.44\$ |
8 |
Step |
After simplification |
r = 3.66 units |
9 |
Step |
The radius of the cone is 3.66 unit |
|
