The diameter of the right circular cone is 8 cm and its volume is 48pi cm^3. what is its height

Solution: Let h cm be the height of the cone .

Diameter of the cone =8 cm

Radius of the cone =4 cm

Now,  Volume of the cone =$\\48\pi$ $cm^3$

$\\ 1/3\times \pi \times 4\times 4\times h=48\pi \\ \\\Rightarrow h=48\pi \times 3/16\pi =9cm$
