That depends on what the 40 foot represents but in general the area of a circle equals pi times radius squared.
A 40-foot by 10-foot yard contains 400 square feet.
Area of the circle: pi*20 squared = 400*pi square feet
40 square feet. Just multiply length by width - the answer is the square footage.
Circumference = Pi x d: 40 = 3.14 x 40 = 125.6 feet
The circumference of a 12-foot-diameter circle is 37.7 feet.
It would probably be pretty wide.
127.324 ft2
That would be 5026.55 square feet.
Radius: 40/2pi = 6.366197724 Area: pi*6.366197724 squared = 127.324 square feet rounded
