Answer:
C=14pi cm
A=49pi cm^2
Step-by-step explanation:
1) Circumference of a circle is 2piR and R=7cm
C=2pi(7)
2) Area of a circle is piR^2 and R=7cm
A=pi (7)^2
x = 0 and y = -6
18.1 is the answer. I am glad I could help.
A. $179.55
Multiply the first equation by -1
-3x-y=-4
2x+y=5
Add them up
-x=1
So x=-1
And y=7
So the first option is correct
I believe that g=dc
You swap positions with g and c along with their sign of operation.
