  1. The volume of a cylinder and a cone are in the ratio 3 : 1. Find their diameters and then compare them when their heights are equal.
    1. Diameter of cylinder = 2 times of diameter of cone
    2. Diameter of cylinder = Diameter of cone
    3. Diameter of cylinder > Diameter of cone
    4. Diameter of cylinder < Diameter of cone
Correct Option: B

=
Volume of cylinder
 =
3
Volume of cone1

=
πr1²h
 =
3
 ⇒ r1 = r2
1
 πr2²h1
3

∴Diameter of cylinder = Diameter of cone
