Problem |
A cylinder has a radius of 7cm and its volume is 1554cm3, what is the height of the cylinder? |
|
2 |
Step |
Given that π (pi) is radius (r) is and volume (V) is |
3.14 7 cm 1554 cm3 |
3 |
Formula: |
Volume of a cylinder |
\$"V" = π times (r)^2 times h\$ |
4 |
Step |
Substitute the value into the formula |
\$1554(cm)^3 = π times (7 cm)^2 h\$ |
5 |
Step |
Solve for h |
\$1554 (cm)^3 = 3.14 times (7 cm)^2 h\$ \$"h" = (1554(cm)^3) / (3.14) times 49(cm)^2\$ \$"h" = 10.09 cm \$ |
6 |
Step |
So, the height (h) of a cylinder is 10.09 cm. |
