Question

The radii of 2 concentric circle are 56cm and 49 cm find the area of the pathway

Answer 1

Answer:

Step-by-step explanation:

π[R^2 -r^2] = π[R+r] [R - r]

                   =  π [ 56+49] [ 56-49]

                    =π [105] [7]

                    =[22/7] [56] [7]

                   = 22[56]

                   =1232
