Q. 48

# A right circular cylinder and a right circular cone have the same radius and the same volume. The ratio of the height of the cylinder to that of the cone is

A. 3 : 5

B. 2 : 5

C. 3 : 1

D. 1 : 3

Answer :

Let height of cylinder and cone be H and h respectively

Given that radii of cone and cylinder are equal

Volume of a cone

Volume of a cylinder =

Given

Ans: 1 : 3

Rate this question :

If *h, S* and *V* denote respectively the height, curved surface area and volume of a right circular cone, then 3π*Vh*^{3}-*S*^{2}*h*^{2}+9*V*^{2} is equal to

A cylinder and a cone have equal radii of their bases and equal heights. Show that their volumes are in the ratio 3 : 1.

RD Sharma - MathematicsA cylindrical bucket, 32 cm high and 18 cm of radius of the base, is filled with sand. This bucket is emptied on the ground and a conical heap of sand is formed. If the height of the conical heap is 24 cm, find the radius and the slant height of the heap.
