Question

If the diameter of a circle is 20 inches, what is the radius?A. 20 feetB. 10 inchesC. 40 inchesD. 20 inches

Answer 1

Given:-

The diameter is 20feet.

To find the radius.

So now we use the formula,

`r=(d)/(2)`

Substituting we get,

`\begin{gathered} r=(d)/(2) \\ r=(20)/(2) \\ r=10 \end{gathered}`

So the required radius is 10 inches.
