How long is the arc subtended by an angle of 7π/5 radians on a circle of radius 25 cm?
Solution:
Given: Radius of the circle is 25 cm
Angle is 7π/5 radians
We know that the arc length is the product of the radius and angle of the circle
⇒ d = rθ
⇒ d = 25(7π/5)
⇒ d = 5(7π)
⇒ d= 35π cm
Therefore, arc length for the given angle 7π/5 and radius 25 cm is 35π cm
How long is the arc subtended by an angle of 7π/5 radians on a circle of radius 25 cm?
Summary:
The arc subtended by an angle of 7π/5 radians on a circle of radius 25 cm is 35π cm.
