Answer:
78.5
Step-by-step explanation:
Formula to find area of a circle: A= pi*raduis to the second power
3.14*
First you square the 5
You do this by multiplying 5 times itself
3.14*25
Then you multilpy 3.14 and 25
78.5
We can use the distribution method for both sides:
9 (x+2) = 5 - 2( x - 1 )
9x + 18 = 5 -2x + 2
Move like terms to one side and combine:
9x + 2x = 5+2-18.
11x = -11
x = -1.
All you have to do is find the length of the sides using the distance formula and then add the lengths together to find the perimeter
