Question

fInd the volume of hollow cylinder for following dimension h= 21 m, R = 20 m , r = 15 m

Answer 1

Answer:

Volume of cylinder = πr²h

Volume of cylinder = 22/7 × 20×20 × 21

Volume of cylinder = 26,400 m³

Answer 2

the formula for finding the volume of of a hollow cylinder is = pi×(R‐r)×h

Step-by-step explanation:

now put the value

22/7×(20‐15)×21 = 22/7×5×21 = 22×5×3 = 330

Hence the answer is 330
