Answer:
sorry bro sorry sorry sorry sorry sorry sorry
X + y = 10
x - y = 2
add the equations together
2x = 12
x = 6
6 + y = 10
y = 3
D = 2r => 12.6 = 2*r => r=6.3
A = π*r^2 = (3.14) * (6.3)^2 = (3.14)*(39.69) = 124.6266 which is approximately 124.63
Hope this helps!
Answer: they are parallel
Step-by-step explanation:
find slope of line m:
Use y2-y1/x2-x1
your m equation --> 9-15/10-3 which makes the slope of m = -6/7
find slope of line n:
Use y2-y1/x2-x1
your n equation --> 3-9/9-2 which makes the slope of n = -6/7
The slopes are the same, therefore line m and line n are parallel.
