Question

wt is the formula for frustum of cone​

Answer 1

Answer:

Step-by-step explanation:

CSA = π×l ( R + r )

TSA = π × l (R + r ) + π (R^2 + r^2)

Volume = 1/3πh(R^2 + r^2 + R×r)

l = √h^2 + ( R - r )^2

R = larger radius

r = smaller radius

l= slant height

h = height of the frustum.

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

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

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