Question

✌what is the formula to find TSA, CSA ☠and volume of a frustum?

Answer 1

CSA of frustum is π(R1 +r2)l.
TSA Of frustum is π(R1+r2)l +πr1^2+πr2^2
volume of frustum is 1/3πrh (r 1 ^2+ r2^2+ R1 r2)

$\Large\mathcal\green{FRUSTUM}$

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

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

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