The radius of the circle is 12cm.
The distance along the part of the circumference of any circle or any curve (arc) is called the arc length of the circle.
The formula for the arc length is
[tex]s = r\theta[/tex]
Where,
s is the arc length of the circle
and θ is the angle in radians
According to the given question.
Length of an arc of the circle, l = 60cm
Angle, θ = 5 radians
Since,
We know that
Arc length = radius × θ
⇒ 60 = radius × 5
⇒ radius = [tex]\frac{60}{5}[/tex]
⇒ radius = 12 cm
Hence, the radius of the circle is 12cm.
