What is radius of a circle?
Its the distance from the center of the circle to the edge of the circle.
What is the formula for radius?
A radius is half of the diameter of a circle, or the distance from one endpoint to the center.
How can you estimate the area of a circle on a grid?
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)
Is a circle named by its center?
No it's made by the circle that how they get the circle not the center.
What formula is used to calculate a circle?
When the radius is r and the center is at (a,b), the formula is (r*cos(θ) + a , r*sin(θ) +b). When the circle is rooted at (0,0), the formula is simply (r*cos(θ) , r*sin(θ)). This is the polar-coordinates system.
What is radius of a circle?
Its the distance from the center of the circle to the edge of the circle.
What is r for the formula for the area of a 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.
What is Pi R Squared?
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.
What is the formula for 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.
How do you write the formula to a circle in the form x?
(x - A)2 + (y - B)2 = C2 (A,B) is the center of the circle. 'C' is the circle's radius.
What is the formula for radius?
A radius is half of the diameter of a circle, or the distance from one endpoint to the center.
What is the formula for area for circle?
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.
What is the radius and the area of a circle?
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.
Is the center of a great circle also the center of a small circle?
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.
What is the radius of the circle if the center of the circle is C(-35) and the point P(511) is on the circle?
If you mean (-3, 5) and (5, 11) then using the distance formula the radius of the circle is 10 units
What is the slant height formula?
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.
What is the formula for 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.
