A circle with a radius of 10 metres has an area of 314.16 square metres.
A circle with a radius of 5455 meters has an area of 93,484,451.13 square meters.
The area of a circle is calculated as A = pi x r2
1,017.9 m2
A = 201 m2
Solve the equation for the area of the circle (area = pi x radius2) for radius. Multiply the radius by 2 to obtain the diameter.
0.757 m
area of a circle = pi * radius² = 1 radius = √(1/pi) circumference = 2pi * radius = 2pi * √(1/pi) = 3.5449077
The area of any circle is (pi) x (radius)2 .A 2-meter telescope has a radius of 1 meter. So its area is(pi) x (1)2 = 3.1416 square meters = about 33.8 square feet.
Using 3.14 as Pi the area of circle is: 0.5024000000000001
The area of a circle with a radius of 14.4 is 651.4
The radius of a circle with the area of 36 is 3.385
