a.A right triangle ABC with sides 5 cm, 12 cm and 13 cm is revolved about the side 12 cm. Find the volume of the solid so obtained.
b. If the triangle ABC in the above Question a is revolved about the side 5 cm, then find the volume of the solid so obtained.
c. Find also the ratio of the volumes of the two solids obtained in Questions a and b.
Given; h = 5 cm, r = 12 cm
Volume of cone = 1/3 π r2 h
= (1/3) π X 122 X 5 = 240 π cubic cm
Ratio = 100/240 = 5 : 12
