Question

The radius of a circle is 7 kilometers. What is the circle's circumference?

Answer 1

The circumference of the circle is 43.96 kilometers.

Explanation:

Alright in otder to fin circumference you need to know the formula for finding the circumference

we know that the perimeter/circumference is equal to the diameter by pi

so the formula

C = 2πr

so input the numbers we have

C = 2(3.14)(7)

Now solve using PEMDAS or BODMAS

you should get...

C = 43.96

So the circumference of the circle is 43.96 kilometers.
