It depends on what information you have.
Its the distance from the center of the circle to the edge of the circle.
A radius is half of the diameter of a circle, or the distance from one endpoint to the center.
Align the circle so that the origin of the coordinate plane is the center of the circle, find the radius, and use the area formula for circles (PI•r^2)
No it's made by the circle that how they get the circle not the center.
It depends on what information you have.
Its the distance from the center of the circle to the edge of the circle.
Area of a circle = pi R2 'R' is the length of the radius of the circle. That's the distance from the center of the circle to any point on the circle.
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.
Formula of a circle in a Cartesian plane: (x-h)^2+ (y-k)^2 = r^2 where the center is at (h,k) and the radius is r.
(x - A)2 + (y - B)2 = C2 (A,B) is the center of the circle. 'C' is the circle's radius.
A radius is half of the diameter of a circle, or the distance from one endpoint to the center.
The formula for the area of a circle is πr2, written in verbal form as: "The value Pi times the radius of the circle squared", where r is the radius (half of the diameter, or the distance from the center to any point on the outer edge of the circle) of the circle, and π equals about 3.1415.
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.
No. Every circle on the sphere whose center is also the center of the sphere is a great circle. If the circle's center is not also the center of the sphere, then the circle is a small circle.
If you mean (-3, 5) and (5, 11) then using the distance formula the radius of the circle is 10 units
The slant height of a cone is given by the formula , where r is the radius of the circle and h is the height from the center of the circle to the apex of the cone.It is trivial to see why this formula holds true. If a right triangle is inscribed inside the cone, with one leg of the triangle being the line segment from the center of the circle to its radius, and the second leg of the triangle being from the apex of the cone to the center of the circle, then one leg will have length h, another leg will have length r, and by the Pythagorean Thereon, r2 + h2 = d2, and gives the length of the circle to the apex of the cone.
