The volume of a cone is 27720 $$cm^{3}$$. If the height of the cone is 20 cm, then what will be the area of the base?
The volume of a cone is 27720 $$cm^{3}$$.
volume of a cone = $$\frac{1}{3}\times\pi\times\left(radius\right)^2\ \times height$$
$$27720 = \frac{1}{3}\times\pi\times\left(radius\right)^2\ \times height$$
If the height of the cone is 20 cm.
$$27720=\frac{1}{3}\times\pi\times\left(radius\right)^2\ \times20$$
$$\frac{27720\times\ 3}{20}=\pi\times\left(radius\right)^2$$Create a FREE account and get:
