Question

A circle has a circumference of 28.26 units. What is the diameter of the circle?

Answer 1

The diameter of the circle is 9.

Explanation:

Because circumference is equal to
`\pi` * d, we can backtrack and use this equation to find diameter. Let's say
`\pi` is equal to 3.14.

28.26 = 3.14d

Divide both sides by 3.14.

9 = d

The diameter of the circle is 9.
