The radius of the circle expressed as a mixed number is: inches.
Radius of a circle = half the measure of the diameter of a circle.
Given:
diameter of a circle = inches
Therefore:
Radius of the circle = 1/2()
= 1/2(47/6)
= (1 × 47)/(2 × 6)
= 47/12
= inches.
Therefore, the radius of the circle expressed as a mixed number is: inches.
