Question

What is the circumference of the circle if the radius is:
5x/3

Answer 1

pir^2

Answer 2

Yes I know the set up I'm just not sure how to solve the problem when it's this way.

Answer 3

oh crap that kinda hard

Answer 4

So you need an x value. Is the x supposed to be pi?

Answer 5

No I dont think x = pi

Answer 6

Is that the whole question? Are you just trying to create a formula for circumference?

Answer 7

No I am trying to solve it and That is the whole question.

Answer 8

Well I might be wrong, but I don't think you can solve for the circumference without an x value. You can solve for x, but I think that is about all you can do.

Answer 9

Circumference = 2 * PI * radius
Circumference = 2 * PI * (5x/3)
Circumference = PI * (10x/3)

Answer 10

I don't think they want an actual, numerical answer.
It's as if they asked "a floor has a width "w" and a length of "l" - What is the area of the floor?"
The answer would be (w*l)

Answer 11

@wolf1728 that is what I was thinking.

Answer 12

I agree
