Answer:
10
Step-by-step explanation:
First make the fractions the same value:
3 and 3/4s is equal to
15/4 which is 30/8s
So,
10 3/8s go into 30/8s
Arc length: s = radius (central angle)
Here, 18 cm = (radius)(7pi/8)
Solving for the radius:
18 cm (18 cm)(8)
radius = --------------- = ------------------ = ? Please calculate this.
(7pi/8) 7pi
