If a radius is 15 inches long, how long is a diameter?
The radius of a circle is half the diameter, thus your measurement is 30 inches
If the diameter of a circle is 12 inches how long is the radius?
Diameter of a circle is defined as twice the radius. So if diameter is 12, the radius is 6.
A chord of a circle is 9 inches long and its midpoint is 6inches from the center of the circle What is the radius of the circle?
Half of the chord, the distance of the midpoint from the center, and a radius, form a right triangle, with the radius as its hypotenuse. (4.5)2 + (6)2 = (radius)2 (20.25) + (36) = 56.25 = R2 Radius = 7.5 inches
