    The inner circumference of a circular path around a circular lawn is 660 m. What is the radius of the outer circumference of the path, if the path is 15 m wide?
    Solutions

    Given, Inner circumference of a circular path = 2πr = 660 m

    ⇒ 2 × (22/7) × r = 660

    ⇒ r = 105 m = inner radius 

    Thus, Outer radius R = r + width of the circular path = 105 + 15

    = 120 m
