Question

The inner circumference of circle is 440 and outer circumference of circle is 506 . Find the width and area of track

Answer 1

The wdth of track is 506-440=66
And area = area of larger circle-area of smaller circle
=22/7*506*506–22/7*440*440
=196227.42857units

Answer 2

inner circumference=440
Πr²=440
22/7×r²=440
r²=140
circumference of circle=506
22/7×R²=506
R²=161
area of track=22/7(R²-r²)
                    =22/7(161-140)
                    =22×21/7
                    =22×3
                    = 66cm²
