In the coordinate plane:
(x - a)2 + (y - b)2 = r2 where the centre of the circle is at (a, b) and the radius is r.
In parametric form, it is
x = a + r*cosΦ
y = b + r*sinΦ
where 0 ≤ Φ < 360 deg.
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
The formula for double the area of a circle
There is none
The formula to get the area of a circle ("R" being the radius of the circle). Radius means the distance from the center of the circle to the edge.It means pi times radius squared which is the formula for finding the area of a circle.
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
The formula is:Volume of a circle = 0
Area formula for circle= --,,- r 2
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
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
The area of a circle can be found with the formula (pi)r^2
The formula for the circumference of a circle is pi * diameter or (2 radius.)
The formula for double the area of a circle
The formula to find the area of a circle is pi x the radius squared.
