Question

The radius of a circular place mat is 7 inches What is the length of its diameter?

Answer 1

We are given the radius of a circle and we are asked for its diameter. To determine that let's remember that the diameter of a circle is double its radius, that is:

`D=2r`

Replacing the value of the radius:

`D=2(7\text{inches)}=14\text{inches}`

Therefore, the diameter is 14 inches.
