A circle with a diameter of 8 inches has a radius of 4 inches. To find the radius of a circle based on a given diameter, divide the diameter by 2. Consequently, to find the diameter, multiply the radius by 2.
Continue ReadingThe radius of a circle is defined as any line segment that connects to the center point of a given circle. The diameter, on the other hand, is any line segment that passes through the center point of a circle, extending from one end to the other. The diameter of a circle is always twice as long as a radius.

Full Answer >The length of an arc of a circle is obtained by using the formula L=?r?/180, where L is the length of the minor arc of the circle, r is the radius of the circle and ? is the angle made by the arc at the center of the circle.
Full Answer >The formula for the area of a circle is pi multiplied by the radius of the circle squared. The radius of the circle is the length of a straight line stretching from the center of the circle to the line of circumference. It is equal to half the diameter.
Full Answer >The calculation of the radius of a circle is expressed by the equation r = C / 2 * pi. This is where r is the radius, C is the circumference and pi is the irrational number beginning with 3.14.
