Area of a circle = pi*radius squared
That depends on what is meant by a 35 foot circle but the area of a circle is pi times radius squared
About 3,848.45 square units.
Using 3.14 as Pi the area of circle is: 961.625
Surface Area = ~4,712.4 ft2
Area of a circle = pi*radius squared
The radius of a circle with an area of 35 mm squared is 3.34mm
The radius of a circle with an area of 35 square inches is 3.34 inches.
That depends on what is meant by a 35 foot circle but the area of a circle is pi times radius squared
A circle with a radius of 35 cm has an area of 3,848.45 square cm.
The area of any circle is determined by the formula: A = πr2 where A is the area, π is "pi", the ratio of a circle's circumference to its diameter (approximately 3.1416), and r is the radius of a circle, or half its diameter. If your diameter is 70 feet, the radius is 35 feet. So, ... A = πr2 = (app) 3.1416 x 352 = (app) 3,848 square feet, or about 0.09 acres.
About 3,848.45 square units.
r = ~3.34 units.
Using 3.14 as Pi the area of circle is: 961.625
Surface Area = ~4,712.4 ft2
70/2pi ie 35/pi = 11.14 ft
radius = 35/(2*pi) in cm
