Problem |
Find the volume of a sphere whose radius is 7.5 in. |
|
2 |
Step |
The given value is radius of sphere is |
7.5 inches |
3 |
Formula |
The volume of a sphere is three fourth of its square radius |
\$3/4 times π times r^3\$ |
4 |
Hint |
Substitute r value in equation, we get |
\$3/4 times π times 7.5^3\$ \$3/4 times 22/7 times 421.875\$ |
5 |
Step |
After simplification |
\$4/3 times 3.5 times 421.875 = 1756.80\$ |
6 |
Step |
The volume of a sphere is \$1756.08 "in"^3\$ |
