Question from kalpaj, a student: A conical funnel holds 100ml. If the height of the funnel is 10 cm, determine |
Kalpaj,
The volume V of a cone is given by
V = 1/3 π r2 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.
