The circumstance of a circle is 2 x pi x radius. I.e.: if the circle has a radius of 6, the circumstances 12×π which is 37.6991118432

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 radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.

Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius

Well to find the radius it is diameter/2.

The area of a circle is given by the formula A = πr^2, where A represents the area and r represents the radius. Plugging in the given radius of 6.2 into the formula, we have A = π(6.2)^2. Evaluating this expression gives an area of approximately 120.79 square units.

The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.

The circumstance of a circle is 2 x pi x radius. I.e.: if the circle has a radius of 6, the circumstances 12×π which is 37.6991118432

If that number represents the diameter, divide it by 2 to get the radius. Then use the standard formula for the area of a circle.

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.

Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12

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

radius = diameter/2

radius = diameter/2.

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.

let the circumference of the first circle be X. The formula for the area of a circle is pi multiple by radius squared. pi can be y so it is yr2. The radius for the second circle is half the diameter so half X. therefore the are is y(0.5X)2. BTW: is this your homework? :)
