Question

The diameter of a circle is 8 mm. What is the circumference of the circle?a.) 25 and 1/7?b.) 50 and 2/7?c.) 11/28?d.) 19 and 1/4?

Answer 1

To answer this question we will use the following formula for the circumference of a circle:

`C=diameter*\pi.`

Therefore:

`C=8mm*\pi.`

Simplifying the above result we get:

`C\approx25.13274123mm`

Now, notice that:

`25.13274123\approx25(1)/(7).`

Answer: Option A.
