Answer:
15cm
Step-by-step explanation:
Arc length is given by:
A=rθ
Where A is arc length.
∴
A=(10) (1.5)
= 15cm
This makes sense, if you consider how we define a radian measurement.
If the radius of a unit circle (radius 1) describes an arc on the circumference equal to its length, then the angle subtended by this arc is defined as 1 radian.
So, if we have a radius of 10cm, and it describes an arc 1.5 times its length, then the length of the arc is 15cm.

Answer:
l=r*theta
where l= length of arc
Step-by-step explanation:
therefore l=10*π/3
