If `r_1` and `r_2` denote the radii of the circular bases of the frustum of a cone such that `r_1> r_2` , then write the ratio of the height of the cone of which the frustum is a part to the height of the frustum.

If h is the height, I the slant height and r_(1), r_(2) radii of the circular bases of the frustum of a cone, then slant height of the frustum = sqrt(( r_(1) - r_(2))^(2) + h^(2)) . Find the height of the cone of which the frustum is a part = (h r_(1) /( r_(1) - r_(2) ).We have a bucket in the form of frustum of a cone in which h = 8 cm, r_(1) = 9 cm and r_(2) = 3 cm.

If h is the height, I the slant height and r_(1), r_(2) radii of the circular bases of the frustum of a cone, then slant height of the frustum = sqrt(( r_(1) - r_(2))^(2) + h^(2)) . Height of the cone of which the frustum is a part = (h r_(1) /( r_(1) - r_(2) ).We have a bucket in the form of frustum of a cone in which h = 8 cm, r_(1) = 9 cm and r_(2) = 3 cm. Find its volume.

The radii of the circular faces of the frustum are 20 cm and 12 cm respectively . If the height of the frustum is 15 cm , then find its slant height.

If the radii of circular ends of a frustum of a cone are 20 cm and 12 cm and its length is 6 cm, then find the slant height of frustum.

The radii of the circulr ends of a frustum of height 6 cm are 14 cm and 6 cm respetively. Find the slant height of the frustum.

If the areas of circular bases of a frustum of a cone are 4\ c m^2 and 9\ c m^2 respectively and the height of the frustum is 12 cm. What is the volume of the frustum?

The radii of the circular ends of a frustum of a cone are 14 cm and 8 cm. If the height of the frustum is 8 cm, find (i) slant height of frustum (ii) total surface area of frustum (iii) Volume of frustum, (pi=3.14)

The radii of the circular bases of a frustum of a right circular cone are 12 cm and 3 cm and the height is 12 cm. Find the total surface area and the volume of the frustum.

The radii of the frustum of a right circular cone are in the ratio 2 : 1. What is the ratio of the volume of the frustum of the cone to that of the whole cone ?
