This problem is solved by first computing the area of the larger circle - the outside of the walk in this case. This circle has a diameter of 22 + 8 m, therefore a radius of 15m. The inner circle has a diameter of 22m - as given - a radius of 11m.
You subtract the area of the inner circle from that of the larger circle.
I'll leave you to do the math.

How many square feet in a diameter of 13 flower bed?
Circles have diameters, so we will assume from your question that it is a circular flower bed. Square feet is a measure of area. Cubed feet is a measure of volume. You need the area of the flower bed that has a diameter of 13 feet. To find the area of a circle you use the formula Area = pi * radius squared Pi is approximately 3.14 The radius of a circle is one half of the diameter of a circle. In your case 13/2 = 6.5 A = pi * r2 A = 3.14 * (6.5)2 A = 132.665 square feet
