A beam of diameter 'd' is incident on a glass hemisphere as shown in the figure. If the radius of curvature of the hemisphere is very large in comparision to d, then the diameter of the beam at the base of the hemisphere will be:

If the diameter of the base of a solid hemisphere is 4d unit. Then the area of whole surface of the hemisphere is

The volume of a solid hemisphere and its curved surface are numarically equal, then the diameter of the hemisphere is

If the total suface area of a hemisphere is 27 pi square cm, then the radius of the base of the hemisphere is

The diameter of a hemisphere is diameter of a sphere. Then the ratio of the volumes of sphere and hemisphere is

A cone and a hemisphere have equal bases and equal volumes. What is the ratio of the height of the cone to the radius of the hemisphere?

The volumes of a solid hemisphere is 144Pi cu. Cm, then find the diameter of the sphere.

A light beam of diameter sqrt(3R) is incident symmetrically on a glass hemisphere of radius R and of refractive index n=sqrt(3) . Find radius of the beam at the base of hemisphere.

A light beam of diameter sqrt(3R) is incident symmetrically on a glass hemispher of radius R and of refractive index n=sqrt(3) . Find radius of the beam at the base of hemispher.
