Answer:
\(r= \frac{d}{2}\)
Step-by-step explanation:
find the expression that relates the measures of the diameter(d) and radius(r)
Diameter of the circle is the line that passes through the center of the circle and endpoints are on the circle
Radius is the line that starts at the center of the circle and ends on the circle
diameter is twice the radius
Diameter = 2* radius
Radius is half of the diameter
Radius = diameter divide by 2
\(r= \frac{d}{2}\)
