Question

If the diameter of a circle is 1 1/2 inches, what is the radius of the circle?

Answer 1

Radius would be 11/4 inches.

Explanation:

The formula for finding radius is `r=d/2` which means you would plug in 11/2 for D and that would result in the decimal form of 2.75, or the fraction form of 11/4 inches.
