Given:
Central angle =
Arc length = 1.5 in
To find:
The radius of the circle.
Solution:
We know that the formula for arc length is
Where r is radius and is the central angle in radian.
Substitute the given values in the above formula.
On further simplifiation, we get
Therefore, the radius of the circle is 1.91 in.
