the radius of a circle field is20m. inside it runs a path 5m wide all around. find the area of the path.(take pai 22/7)

Answers & Comments

umang95 Area of circular path = π(R-r)
R = radius of outer circle
r= radius of inner circle i.e R - width of the path

therefore
Area = 22/7 × (20-15)
= 22/7 × 5 = 15.71 sq m
= 16 sq m (approx)
