# If the volume of a right circular cone of height 9 cm is 48π cm^{3}, find the diameter of its base.

Answer :

We have ,

Volume of cone = 48π cm^{3}

Height of cone h = 9 cm

= 1/3πr^{2}h = 48π

= r^{2}= 16 r = 4 cm

Hence diameter of its base = 2 × radius = 2×4 = 8 cm

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.
