The formula to figure out the circumference of a circle is C=2(pi)r. So with a circle that has a radius of 40 inches, you can set up the formula like: C=2(pi)40. To figure this out on a calculator, multiply 2 with pi and then multiply that answer with 40. If you do not have a pi symbol on your calculator you can multiply 2 with 3.14159 then multiply that answer with 40.

If a circumference of a circle is 28.26 inches what is the radius of the circle?
Well, isn't that a happy little question! To find the radius of a circle when you know the circumference, you can use the formula: circumference = 2πr. So, if the circumference is 28.26 inches, you can plug that in and solve for the radius. Just divide the circumference by 2π (which is about 6.28) to find the radius. Happy calculating!
