Answer» dth of the CIRCULAR path = h Let the radius of inner circle= R Then radius of OUTER circle = (r + h) Area of inner circle = πr2 Area of outer circle = π(r + h)2 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)] (∵ A2 – b2 = (a + b)(a - b) |
