Question

A path of uniform width 3 m runs outside around a circular park of radius 9 m. Find the area of the path​

Answer 1

Answer:

Step-by-step explanation:

To be clear

Take the initial radius as 9m

The are is π [9]^2 =81π

Then take the external circle radius 9+3 = 12

The area is π (12)^2 =144π

The area of the path is 144π - 81π

63π = 197.9 m

So the area is 197.9m
