Answer:
Radius of the circle is 3.07 in ( inches).
Step-by-step explanation:
The mathematical formula representing the relationship between radius and central angle is given as :
S = rθ
Where S is the length of the arc in inches (in)
r is the radius of the circle
θ is the central angle in radians
Given that from the above question,
S = 3.07 inches
Central angle (θ)= 1 radians
Radius = unknown which is represented by r
Therefore,
3.07in = 1r
Therefore, r = 3.07 ÷ 1
r = 3.07in (inches)
The radius of the circle is 3.07in (inches)
