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.
