Question

Frustrum ke formulae batao plzzzzz
urgent hai !!!!!!!!​

Answer 1

Step-by-step explanation:

The curved surface area of the frustum of the cone = π(R+r)l

Answer 2

Answer:

In geometry, a frustum[1] (plural: frusta or frustums) is the portion of a solid (normally a cone or pyramid) that lies between one or two parallel planes cutting it. A right frustum is a parallel truncation of a right pyramid or right cone.[1]

In computer graphics, the viewing frustum is the three-dimensional region which is visible on the screen. It is formed by a clipped pyramid; in particular, frustum culling is a method of hidden surface determination.

In the aerospace industry, a frustum is the fairing between two stages of a multistage rocket (such as the Saturn V), which is shaped like a truncated cone.

If all the edges are forced to be identical, a frustum becomes a uniform prism
