24 degrees = 24 * pi/180 = pi*(2/15) radians
(arc length)/radius = pi*(2/15)
radius = (8 pi)/[(2/15)*pi]
= 60
I think this will be the last one.
Find the radius of circle C if the measure of anglePQR=24° and the length of arc PR is 8pi.
Answers:
a.15 b.20 c.30 d.60 e.45
The diagram looks like a circle with its center at C. At a point on the edge of the circle is Q with lines reaching out to P and R at 24°. The arc between them is 8pi. Hope that helps
