Question

what's the formula for finding (pi) in terms of the circumference and radius?

Answer 1

In circles the AREA is equal to 3.14 (p) times the radius (r) to the power of 2.
Thus the formula looks like:
A= pr2.

Answer 2

I think he's asking for the circumference, 2pir, not area :s

Answer 3

π = C + 2r is that it?

Answer 4

Oh. xD I fail because that's how I learned it. Nevermind then.
@Student890 You got it right. That's what I meant. But i learned both. Dx Fail.

Answer 5

pi = c/2r
since C = 2pir

Answer 6

Oh don't worry about it! I'm not sure if it's that one or π = C divided by two r

Answer 7

It's π = C divided by two r
