Answer:
Option D. 
Step-by-step explanation:
step 1
Find the midpoint of the given line segment
we know that
The formula to calculate the midpoint between two points is equal to
we have

substitute the values
step 2
Find the equation of the perpendicular bisector
we know that
The equation of a perpendicular bisector is equal to the x-coordinate of the midpoint, because is a vertical line (parallel to the y-axis)
therefore
the equation is equal to

2(pi)r
2(pi)0.75
Circumference is 4.71.
Answer:
C. 55 inches
Step-by-step explanation:
a^2 = b^2 + c^2
a^2 = 47.5^2 + 27^2
a^2 = 2985.25
a = 54.637 = 55 inches
