What is the circumference of a circle in terms of pi with a radius of 2.2?
I know that c = 2 pi * r
c = 2 pi * 2.2
c = 2 * 2.2
my answer is 4.4 pi
You're welcome.
Right.
thank you

Well, I hate to burst your bubble, but your answer is as flat as a pancake. Let's go through it one more time, with a little extra flair.
The formula you mentioned, c = 2πr, is spot on! But your calculations took a detour somewhere.
For a circle with a radius of 2.2, the circumference would be:
c = 2π(2.2)
c = 4.4π
Ah, now we're cooking with gas! The correct answer would be 4.4π, without any need for improvement or meddling. So, keep that circle spinning and remember, math can be a circus, but it's always worth it!
To find the circumference of a circle with a radius of 2.2 in terms of pi, you can use the formula: c = 2 * pi * r.
In this case, the radius (r) is 2.2.
Substituting this value into the formula, you get: c = 2 * pi * 2.2.
Evaluating this, you get: c = 4.4 * pi.
Therefore, the circumference of the circle is 4.4 pi units.
