Answer:
131.6
Step-by-step explanation:
X + 5y + 2 - 7x + 5y + 2y - 7x
First collect like terms (the numbers that have the same letters after them):
x - 7x - 7x = -13x
5y + 5y + 2y = 12y
Then put these back into the expression:
2 - 13x + 12y
The formula for the circumference of a circle is:
C=2πr
Since we know the radius is 14cm, we can solve for the circumference...
C=2π(14)
C=28πcm
C=<span>87.96cm</span>
