The radius of a circle is 3 units. If its circumference is aπ units, what is the value of a?

Answer 1

Greetings! Lets solve this shall we ?

So, we must find the value of a using the given information such that the Circumference is

C =

2πr = aπ........Divide by π to get

a = 2r.........Then plug in 3 for r to get a such that

a = 2(3)

a = 6

I hope this helped!
