Question

ANY ONE SAY ME WHAT IS FRUSTUM OF CONE AND WHAT IS THE FORMULA OF CURVED SURFACE AREA, TOTAL SURFACE AREA AND VOLUME OF FRUSTUM OF CONE....................
PLZZZZZZZZZZZZZZZZZZ URGENTLY

Answer 1

TSA of a frustum = pie * l( radius of the bigger diameter + radius of the smaller diameter) + pie r1 square + pie r2 square
LSA of a frustum = pie ( r1 + r2) l
volume of the frustum = 1/3pie *h ( r1 square + r2 square + r1*r2)

$\Large\mathcal\green{FRUSTUM}$

$\implies \: tsa = \pi \: l(r1 + r2) + \pi \: {r1}^{2} + \pi {r2}^{2}$

$\implies \: csa = \pi \: l(r1 + r2)$

$\implies volume = \frac{1}{3}\pi \: h( {r1}^{2} + r1.r2 + {r2}^{2} )$
