To find the diameter of a circle with an area of 3 acres, we first convert acres to square feet. One acre is 43,560 square feet, so 3 acres equals 130,680 square feet. The area ( A ) of a circle is given by the formula ( A = \pi r^2 ). Solving for the diameter ( d ) (where ( d = 2r )), we find that the diameter is approximately 404.3 feet.
There are: pi*20.52 = 1320.254 square feet to 3 decimal places
Area = pi*5.52 = 95.033 square feet to 3 d.p.
A 45-foot diameter circle has an area of 1,590.4 square feet.
There are about 38.48 square feet in a 7' diameter circle

A cylinder with a diameter of 1 foot and 3 feet high has a surface area of 11 square feet.
There are: pi*20.52 = 1320.254 square feet to 3 decimal places
Area = pi*5.52 = 95.033 square feet to 3 d.p.
A 45-foot diameter circle has an area of 1,590.4 square feet.
There are about 38.48 square feet in a 7' diameter circle
if the diameter is in feet then multiply the diameter by pi 38 x 3.14159 = 119.38042 square feet if the diameter is in inches then dividethe inches by 12 then multiply the diameter by pi 38 ÷ 12 = 3.16666 x by 3.14159 = 9.94835 square feet
7.0686 square feet for a 3-foot diameter circle.
A square yard can represent a square with dimensions of 3 feet by 3 feet. Therefore a 7 foot diameter gasket cannot be cut out of a square yard. If you meant 7 inches diameter, then you will be able to cut 25 gaskets from 3 feet by 3 feet but you may even be able to cut 26 gaskets if the square yard was a rectangle of 7 inches wide (by 185 inches long).
A circle that has an area of 78.5 square feet has a diameter of 10 feet.
The diameter is 4.222 feet.
