Make sure you know the formula pertaining to the question.
1. c=2(pi)(r)
2. c=2(pi)(d)
r= radius
d= diameter
c= sircumference
So we are given that the circumference of a circle is 12.3pi and the radius is unknown.
So let's plug in the known values
**we use the formula with the radius, becuase we are looking for the radius.
c=2(pi)(r)
12.3(pi)=2(pi)(r)
divide each side by pi
12.3=2(r)
divide each side by 2
r=6.15 in.

Answer:
40degrees
Step-by-step explanation:
Find the diagram attached
Since the triangle ina semi circle is a right angle, hence <B = 90degrees
Also frm the diagram
<A + <B + <C = 180
<A + 90 + 50 = 180
<A + 140 = 180
<A = 180 - 140
<A = 40degrees
Hence the measure if m<BAC is 40degrees
