Question

csa , tsa and volume of frustrum

Answer 1

Answer:

C.S.A of frustum = πl ( r1 + r2 )

T.S.A of frustum = πl (r1 + r2 ) + πr1^2 + πr2^2

Volume of frustum = 1/3 πh ( r1^2 + r2^2 + r1r2)

Plz mark me as a brainlist.....

Answer 2

Answer:

Step-by-step explanation:

volume of frustum=1/3$\pi$h($r^{2}$+$R^{2}$)(Rr)

TSA of frustum = $\pi$l(r+R)+$\pi$$R^{2}$

LSA of frustum =  $\pi$l(r +R)
