Answer:
8π miles
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = 2πr
For a radius of 4 miles, the circumference is ...
C = 2π(4 miles) = 8π miles
3 - 3/5
Cosine = adjacent/hypotenuse
So, in this case, cos=6/10=3/5
19. y=-3x+5
20. y=1.75x+7
36 blues
5x + 2y = -15
2y = -15-5x
y = -5/2x-15/2
SLOPE: -5/2
