Take the circumference of a circle and divide it by the diameter of that circle: ∏=C/D
of what? Does it really take that much longer to type in "of a circle".
-- Take the formula for the area of the circle in terms of the radius . . . A = (pi) R2-- Solve that formula for 'R'. You'll then have a formula for the radius in terms of the area,which is exactly what you're looking for.
The formula is:Volume of a circle = 0
Area formula for circle= --,,- r 2
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
Yes the great circle formula is the same formula for any other circle.
There is no specific formula for a sector of a circle. There is a formula for its angle (at the centre), its perimeter, its area.
The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.
the formula for the area of a circle is 3.14 x radius squared
The formula to find the area of a circle is: A = pi * r2
You take half the area of a circle in square feet. The formula is: 1/2 * pi * (radius)2
