find the length of an arc of a circle whose central angle is 3 radians and it’s radius is 8 cm
The formula to find the length of an arc of a circle is:
L = rθ
Where L is the length of the arc, r is the radius of the circle, and θ is the central angle in radians.
In this case, the central angle is 3 radians and the radius is 8 cm. So:
L = 8 x 3
L = 24 cm
Therefore, the length of the arc is 24 cm.
