Answer:
C = 60pi cm or approximately 188.4 cm
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
C = 2* pi * 30
C = 60 pi
We can approximate pi by 3.14
C is approximately 60*3.14 or 188.4

I got it right when I was doing the assignment :)
Answer:
y=-3x-3
Step-by-step explanation:
To get a perpendicular line you take the negative reciprocal of the slope, so in this case it would equal -3. Now use point-slope form to get your equation. Point slope form says that y-y1=m(x-x1) where m is your slope and x1 and y1 are the points that the graph passes through. So in this case x1=-3, y1=6, and m=-3. This gives you the equation y-6=-3(x+3). Distribute to y-6=-3x-9, and finally add 6 to both sides to get y=-3x-3
