Answer:
C = 28.048
Step-by-step explanation:
Circumference = 2pi(r)
Area = pi(r)^2
62.6 = pi(r)^2
r^2 = 62.6/pi
r^2 = 19.926
r = 4.464
Therefore, circumference = 2pi(4.464)
= 28.048
1) 90 degrees, if it rotated 3 more times to that degree in the same direction it would end up where it started
2) 180 degrees
3) 270 degrees (three 90 degrees)
6 has rotational symmetry and the other ones don't

Answer:
y = -x - 1
Step-by-step explanation:
hello,
this is a line, right?
So the equation should be something like
y = ax+b and we need to find a and b
we can see that the points (-1,0) and (0,-1) are in the line so we can write
0 = a*(-1) + b <=> b - a = 0 <=> a = b
-1 = a*0 + b <=> b = -1
so the equation is
y = -x - 1
hope this helps
You could simplify it to be 1:3 by multiplying both sides by 6
