Answer 1

Answer:

2πr^2h

..................

Answer 2

Step-by-step explanation:

In case of hollow cylinder, we measure two radius, one for inner circle and one for outer circle formed by the base of hollow cylinder. Suppose, r1 and r2 are the two radii of the given hollow cylinder with 'h' as the height, then the volume of this cylinder can be written as; V = πh(r12 – r22)
