What is the exact circumference of a circle with a radius of 12 inches?

Answer 1

The formula for the circumference of a circle is C = 2\(\pi\)r, so what do you think the answer is?

Answer 2

75.4in is the anwser

Answer 3

So when we plug in the values into the equation, we get 2 x 3.14 x 12. Can you figure that out?

Please refrain from giving direct answers again. Thank you. :)

Answer 6

The formula is \(C = \pi d\)

Where 'd' is diameter.

Answer 7

What's 12 * 2?

Answer 8

@iGreen. That's wrong.

Answer 9

No, it's not.

2 * r is the same thing as the diameter.

Answer 10

@lordoftanks Can you multiply 12 * 2?

Answer 11

The formula is actually C = 2 x pi x radius

Answer 13

Oh, we're pretty much using the same thing.. lol

Answer 14

ooo thx

Answer 15

@lordoftanks Can you multiply 12 * 2? That will give you your answer in terms of pi.

Answer 16

Because the one I am using uses multiplies it to 2, and the radius is half the diameter, so we get the same answer.

Answer 17

That's what I said.
