It is the centre of the circle. The size of the radius makes no difference.
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
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
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
x2 + y2 = r2, where r is the radius.
False because that would be the diameter of the circle.
R = Radius The radius is half the diameter of a circle.
