Square footage of path = (pi*92)-(pi*72) = 100.531 square ft rounded to 3 dp
The square footage of a radius is meaningless, but if you mean the square footage of a circle of radius say R, the answer is 3.142 x R x R
If it's a circle, around 1017.88 square feet.
56.547
Multiply the radius by 2, then by the value of Pi - and you'll have your answer !
If you want to find the size of your circular garden you will need a scientific calculator to do some sums. here are the methods.The area of the garden is equal to Pi times the square of the radius. To find the radius, measure from the edge of the circle to it's middle point, cutting a slice of cake.The circumference of the garden (the length of it's outer edge) is equal to Pi times it's diameter. To find the diameter, measure the length from one side to the other, cutting through the center point.
The diameter is twice the length of radius, so it is 28 feet.
How much fencing is required to enclose a circular garden with a radius of 14 meters? (Use 3.14 for π) _
176 m of fencing. Area of circle = 2*pi*radius
50 pi meters
Approx 25.13 metres.

Circumference=2pir=2x3.1416x30 ft=188ft Length of each side = circumference/4=188 ft/4=47 ft Answer: 47 feet

Distance around circle = 2*pi*r = 157.1 so r = 157.1/(2*pi) = 25.00 ft so, to the nearest tenth of a foot, 25.0 ft
