BASIC INFORMATION ABOUT FRUSTUM.
• In geometry, a frustum (plural: frusta or frustums) is the portion of a solid (normally a cone or pyramid) that lies between two parallel planes cutting it. A right frustum is a parallel truncation of a right pyramid.

SURFACE AREA OF FRUSTUM
TOTAL SURFACE AREA OF A FRUSTUM:П(R+R)L + ПR 2 + ПR 2
=П(R+R)L + П(R 2+ R2)CURVED SURFACE AREA OF A FRUSTUM:
П(R+R)L

VOLUME OF FRUSTUM
VOLUME OF A FRUSTUM:1/3 ПH(R 2+R 2+RR)

A FRUSTUM MAY BE FORMED FROM A RIGHT CIRCULAR CONE BY CUTTING OFF THE TIP OF THE CONE WITH A CUT PERPENDICULAR TO THE HEIGHT, FORMING A LOWER BASE AND AN UPPER BASE THAT ARE CIRCULAR AND PARALLEL. CONSIDER THE RIGHT CIRCULAR CONE.LET H BE THE HEIGHT, R THE RADIUS OF THE LOWER BASE, AND R THE RADIUS OF THE UPPER BASE. ONE PICTURE OF THE FRUSTUM IS THE FOLLOWING.GIVEN R, R, AND H, THE VOLUME OF THE FRUSTUM WILL BE-1/3 ПH(R 2+R 2+RR)

QUESTION BASED ON FRUSTUM.
• Question 1: A drinking glass is in the shape of a frustum of a cone of height 14 cm. The diameters of its two
circular ends are 4 cm and 2 cm. Find the capacity of the glass.• ANSWER- Capacity of glass = Volume of frustum of cone
• Therefore, the capacity of the glass is.
