Assuming you are referring to a circular area, the diameter is 37.01 feet.

A circular shape with an area of 65 square feet has a diameter of 9.1 ft approx.

The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.

200.96 square feet.

Area: pi*2.6^2 = 21.237 square inches rounded

Area of the circle = pi*62 = 113.097 square feet to 3 decimal places

Divide the diameter by two to get the radius. Then you can use the standard formula for the area of a circle, which I copy here for your convenience: area = pi x radius squared

Area = pi*12.252 = 1847.453 square meters rounded to 3 dp

750,000 circular mils. A wire that is 1 mil (.001 inches) in diamter is defined to have an area of 1 circular mil. The area in circular mils = (diameter in mils) ^ 2. To convert this to area in square inches, multiply 750,000 * pi / 4,000,000 = 0.589 sq in.

Assuming the area in question in circular, area = pi*r*r where r, the radius is half the diameter. area = pi*7.5*7.5 = 176.7 square feet.

Divide the known circumference by the value of Pi - and you'll have your answer !

The lateral area of a right circular cone with a base diameter of 4 m and a slant height of 15 m is: 94.25 m2

1 circular mil = 1 mil x 1 mil a=d2 so if a wire has a diameter of 80 mils, it has an area of 6400 circular mils.
