The circumference of the outer circle is greater than that of the inner circle by 18.86 feet.
A circle is a round 2-dimensional shape. It is a closed shape with a distance from center to circumference termed as radius 'r' and distance from one point on the circumference to another point passing through center termed as diameter 'd'.
The circumference of the inner circle is 88 ft.
Circumference of a Circle = 2πr
2πr = 88
2 X 22/7 X r = 88
r = 88 X 7 / 44
r = 14 ft.
Radius of the inner circle = 14 feet
If the distance between the inner circle and the outer circle is 3 ft, the radius of the outer circle = 14+3 = 17 feet.
circumference of the outer Circle = 2πr
= 2 X 22/7 X 17
= 106.86 ft.
Difference in Circumference = 106.86 - 88 = 18.86 feet
Thus, the circumference of the outer circle is greater than that of the inner circle by 18.86 feet.
