Circumference of a circle =
They are all multiplied by each other
r = radius
we know our radius is 40
and...
= 3.14
so we would use this expression 3.14 x 40 x 2 As a added bonus ill solve it for you :P
3.14 x 40 x 2 = 251.2
The circumference of this ice skating rink is 251.2 feet
<h3>The answer is:</h3><h2>7.5 degrees</h2>

Answer:
10x + 4
Step-by-step explanation:
Combine like terms.
First combine the numbers that have the letter x:
- <u>-3x</u> <u>+ 8x</u> + 2 <u>- 3x</u> <u>+ 8x</u> + 2
- <u>-3x + 8x -3x +8x</u> + 2 + 2
- <u>10x</u> + 2 + 2
Then combine the ones that don't have the letter x
- 10x <u>+ 2</u> <u>+ 2</u>
Answer is 10x+4
