Question

3. Write the formulae to find
CSA, TSA and Volume of
cone,cylinder hemisphere,
sphere and explain the terms
in them.​

Answer 1

Answer:

CSA=2πr

TSA= 2πr²

hope it will help you

Answer 2

Answer:

csa of cone = pi r l. csa of cylinder = 2pi rh. csa of sphere = 4. pi r square

Step-by-step explanation:

tsa of cone pi r (h+r) . tsa of cylinder = 2 pi r (r+h) . volume of cone 1/3pi r square h volume of cylinder = pi r square h. volume of sphere = 4/3 pi r square h
