There are 2 formula to find the circumference of a circle.

\huge{\boxed{\bf{Circumference=2\pi r}}}

\huge{\boxed{\bf{Circumference=\pi D}}}

\pi is approximately 3.14
r is radius
D is diameter

and just a side note, \huge{\boxed{\bf{2 r = D}}}
Hope that formula helps you :)

Answer:

2rPi:

Step-by-step explanation:

You can multiply the radius by 2, which gives you the diameter. Then you multiply by Pi, which is 3.14 OR 22/7. If you are in Khan Academy, don't use 22/7.

What multiplication expression can be broken apart into (3x4) + (3x4) using the distributive property
Anna007 [38]
The original expression here might be (4x3) + (4x3). This is because the distributive property simply moves around numbers, but will not change the value of the equation, as in the question we are looking at here.
