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.

To find the amount of fencing required to enclose a circular garden, you need to calculate the circumference of the circle. The formula for the circumference ( C ) is ( C = 2\pi r ), where ( r ) is the radius. For a garden with a radius of 70 m, the fencing required would be ( C = 2\pi(70) \approx 439.82 ) meters. Therefore, approximately 440 meters of fencing is needed.
Multiply the radius by 2, then by the value of Pi - and you'll have your answer !
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
Approx 25.13 metres.
50 pi meters
