The measures of the diameter and the radius, are illustrations of unit conversions
The radius of the circle is 9 inches
The diameter (d) is given as:
[tex]\mathbf{d = \frac{1}{2}\ yard}[/tex]
Multiply by 36 to convert the unit from yard to inches
[tex]\mathbf{d = 36 \times \frac{1}{2}\ inches}[/tex]
[tex]\mathbf{d = 18\ inches}[/tex]
Divide both sides by 2, to get the radius
[tex]\mathbf{r = \frac{d}{2} = \frac{18}{2}\ inches}[/tex]
[tex]\mathbf{r = 9\ inches}[/tex]
Hence, the radius of the circle is 9 inches
