# A right triangle

Answer :

Concept Used: Volume of cone Where r = radius of the cone and h = height of the cone.

Given: Dimensions of a right-angled triangle.

Hypotenuse = 13 cm

Base = 5 cm

Perpendicular = 12 cm

Explanation:

When right-angled ΔABC is revolved about its side 12 cm then a cone is formed having

Height (h) = 12 cm

Radius (r) = 5 cm

Slant height (l) = 13 cm Volume  = 100 π cm3

Hence, the volume of the figure is 100 π cm3.
