1 |
Problem |
The volume of a cylinder is \$ 458 mm^3\$ and the radius is 7.8 mm and find the height of a cylinder. |
|
2 |
Step |
The given values are |
V = 458 and r = 7.8 mm |
3 |
Formula: |
The volume of cylinder is |
\$V = π times r^2 times h\$ |
4 |
Step |
Now substitute the values |
\$458 = 3.141 times (7.8)^2 times h\$ |
5 |
Step |
After simplification |
\$ 458 = 3.141 times 60.84 times h\$ |
6 |
Step |
After simplification |
\$ 458 = 191.09 times h\$ |
7 |
Step |
After simplification |
\$ h = 458 / 191.09\$ |
8 |
Step |
After simplification |
h = 2.39 mm |
9 |
Step |
The height of the cylinder is h = 2.39 mm |
