Question

A right triangle ABC with the side 5cm,12cm, and 13cm is revolved about the side 12cm. find the volume of the solid so obtaind????​

Answer 1

Answer:

The volume of the cone is 314.28 cm³ (approx.)

Step-by-step explanation:

When right angled triangle is revolved along one of its axis, the solid so obtained will be a cone

Height of cone (h) = 12 cm

Radius of cone (r) = 5 cm

Volume of cone = 1/3 π r² h

                           = 1/3 × 22/7 × 5 × 5 × 12

                           = 2200/7

                           = 314.28 cm² (approx.)
