Its the distance from the center of the circle to the edge of the circle.
The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
x2 + y2 = r2, where r is the radius.
the radius of a circle is r
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.
The equation of circle is (x−h)^2+(y−k)^2 = r^2, where h,k is the center of circle and r is the radius of circle. so, according to question center is origin and radius is 10, therefore, equation of circle is x^2 + y^2 = 100
R (radius) X2. The radius is half the circle from the center of the circle. The diameter is just straight across.
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.
Its the distance from the center of the circle to the edge of the circle.
The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2
d/2=r
circumference is the distance around a circle diameter is the distance from one point on the circle, straight across to the other side. radius is distance from the center of the circle to any point on the circle radius = r diameter = 2r circumference = 2(pi)r pi = 3.1415927
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
x2 + y2 = r2, where r is the radius.
R = Radius The radius is half the diameter of a circle.
The relationship between the chord and the radius of the circle is Length of the chord = 2r sin(c/2) where r = radius of the circle and c = angle subtended at the center by the chord
