Find the circumference of a circle with a diameter of 20 inches.

The circumference of a circle can be found with this equation:

C = 2r

"r" is the radius, which is half of the diameter.

The diameter is 20.

20 ÷ 2 = 10

Your radius is 10. Now that you know the radius, you can plug it into the equation:

C = 2r

C = 2(10)  Multiply 2 and 10 together

C = 20

Your circumference is:

20 inches  or  62.8318530718 inches(you should round it if you want lol)

is there any photos or whatever?

step-by-step explanation:

6 (donuts) divided by 3 is 2.
