Answer:
about 19.92 meters
Step-by-step explanation:
The circumference is ...
C = πd
72 m = πd . . . . . for outer diameter d
d = (72 m)/π
The inner diameter is 3 meters shorter, so is ...
inner diameter = (72/π) m - 3 m ≈ 19.92 m

Answer:
-44 4/9
Step-by-step explanation:
-36 4/9-(-10 2/9)-(18 2/9)
-36 4/9+10 2/9 = 26 6/9
26 6/9 - (18 2/9)= -44 4/9
Y=-1/3-2 because you have to make the slope into a negative inverse and the y-intercept stays the same because it's perpendicular.
Normal:3
Negative inverse: -1/3
