Question

a right triangle ABC with sides 5 cm, 12cm, and 13cm is revolved about the side 12 cm find the volume of the solid so obtained.

Answer 1

Answer:

754.28 cm^3

Explanation:

Radius= 12cm

height= 5cm

when revolving it is forms a cone

so, vol of cone=1/3*22/7*r^2*h

                        =1/3*22/7*(12)^2*5

                        =1/3*22/7*144*5

                        =754.28cm^3
