The diameter of a circle is the distance across a circle directly through its center. The radius is one half of the diameter in measurement. The radius measures the distance from the very center of the circle to any point on the circle. You can calculate either of the measurements if you ...

The general relationship between radius and the diameter is that the radius is half of the diameter. r=d/2. So, now if you know the width of the circle, otherwise called the diameter, you can simply divide it by 2 to get the radius. If the diameter of a circle is 8.8cm, then the...

The given end points of the diameter are ( (8,6)) and ( (2,0)). The center point of the circle is the center of the diameter, which is the midpoint between ( (8,6)) and ( (2,0)). In this case the midpoint is ( (5,3)). ( (5,3)) Find the radius( r) for the ...
Find the exact radius of a circle whose circumference is 28 \pi \; \textrm{m}. If the circumference of a circle is 32 in., find the radius of the circle. (a) 16 in. (b) 10.2 in. (c) 2.54 in. (d) 5.1 in. How to calculate the diameter of a circle given only the...
Find the centre of a circle passing through the given points and also find the radius of it. How do you find the diameter and center point of a circle given two end points? Find the radius of a circle from the equation (x+4)^{2}+(y-7)^{2}=196. ...
The radius is used to define the diameter, circumference, and area of the circle. The diameter of the circle is a straight line through the center point. So, the length of a diameter is given by twice the radius. That is, d=2r. Circles have an angle of 2π and a radius of r. ...
