Answer:
RPS =19
Step-by-step explanation:
A right angle is 90 degrees
The two angles add to a right angle or 90 degrees
RPS + QPR = QPS
RPS + 71 = 90
RPS = 90-71
RPS =19
8.50 / 12 = 0.708 rounded to the nearest cent = 71 cents (0.71)
Formula to find circumference is ;

Since the given circumference is 30 pi then,
30 pi = 2 pi radius.
30 = 2 radius
radius = 30/2
radius = 15
The radius is 15 for a circle tha has circumference of 30 pi
