Remark

I hope all you want is the radius of the circle. If you want more, we'll need the pictures.

If a chord is 10 inches long, then the distance from the center of the chord the center of the circle is given as 5 inches. Distance in this instance is thought of as the shortest distance from the center of the circle to the chord. Thus 5 inches.

The center of the chord to the center of the circle is one side of a right triangle. 1/2 the distance of the chord is another side of a right triangle. The radius is the third side.

a = 5

b = 5

c = ??

Formula

a^2 + b^2 = c^2

Sub and solve

c^2 = 5^2 + 5^2

c^2 = 25 + 25 Combine the right

c^2 = 50 Take the square root of both sides.

sqrt(c^2) = sqrt(50)

sqrt(c^2) = sqrt(25 * 2)

sqrt(c^2) = sqrt(25) * sqrt(2)

c = 5 * sqrt(2) = radius <<<<< Answer.
