The volume of a right circular cone is 3080 $$cm^{3}$$. If the radius of its base is 7 cm, then what is the height of the cone? (in cm) [Use $$\pi = \frac{22}{7}$$]
The volume of a right circular cone is 3080 $$cm^{3}$$. If the radius of its base is 7 cm.
the volume of a right circular cone =Â $$\frac{1}{3}\times\ \pi\ \times\ \left(radius\right)^2\times\ height$$
$$3080=\frac{1}{3}\times\frac{22}{7}\times\ \left(7\right)^2\times\ height$$
$$3080=\frac{1}{3}\times22\times7\times\ height$$
$$20=\frac{1}{3}\times height$$
height of the cone = $$20\times3$$ = 60 cm
