Question

A circle has a radius of 12 cm. What is the circumference of the circle?

Answer 1

Let's recall the formula for getting the circumference of a circle:

`\text{Circumference = 2}\pi r`

Given that the radius of the circle is 12 cm, we get:

`\text{Circumference = 2}\pi r`
`\text{ = 2}(3.14)(12)`
`\text{Circumference = 7}5.36\text{ cm}`

Therefore, the circumference of a circle that has a radius of 12 cm is 75.36 cm.
