Answer:
Step-by-step explanation:
Given two concentric circles with radius r and (r + h)
Area of outer circle = π(r + h)2
Area of inner circle = πr2
Area of circular path = area of outer circle – area of inner circle
= π(r + h)2 – pr2
= π[(r + h)2 – r2]
= π[(r + h + r)(r + h – r)] (Since a2 – b2 = (a + b)(a - b)]
= π(2r + h)(h)
= πh(2r + h)
