Question

What is the CSA, TSA and volume of a frustum?

Answer 1

csa =π[R+r] l
tsa =π[(R+r) l +R^2 + r^2]
volume = πh÷3 (R^2 +r^2 +Rr)

Answer 2

FRUSTUM:
• CSA = πrl
---------------------------------
• TSA = πrl+πr^2
= πr(l+r)
--------------–------------------
• Volume = 1/3 × πr^2h
= πr^2h/3
----------------------------------

hope this helped,
plzzz mark as brainliest .......!
