The difference between circumference and diameter of circular plot is 105m. Find the area of the circular plot.

Given: Difference between circumference and diameter of circular plot = 105m


We know that,


The circumference of a circle = 2πr


and diameter of circle = 2r


According to the question


2πr – 2r = 105


⇒ 2r(π – 1) = 105



Now, Area of circular path = πr2







= 1886.5m2
