A conical funnel holds 100ml. If the height of the funnel is 10 cm, determine
its radius, to the nearest tenth of a centimeter.

Kalpaj,

The volume V of a cone is given by

V = 1/3 πr^{2}h

where r is the radius and h is the height. One milliliter is one cubic centimeter and hence you have h = 10 cm and V = 100 cc. Substitute these values in the the volume equation and solve for r.
