Question

Find the volume of a cone if the radius of its base is 1.5 cm and its perpendicular height is 5 cm.

Answer 1

Radius of the cone, r = 1.5 cm

Height of the cone, h = 5 cm

∴ Volume of the cone, V = $\frac{1}{3}\mathrm{\pi }{r}^{2}h=\frac{1}{3}\times \frac{22}{7}\times {\left(1.5\right)}^2\times 5=$11.79 cm³

Thus, the volume of the cone is 11.79 cm³.
