Question
A circular park is having the circumference of 110m. A
uniform path of width 3.5m has been made around the park. Find the area of this path?Solution
Radius of the park (r): 2×22/7×r = 110 => r = 35/2 Radius of park including the path = 35/2 + 7/2 = 42/2 = 21 Area of this path = 22/7 × (212 - 17.52) = 423.5
