find the radius of a circle whose arc length is 51 cm and it’s central angle is 3 radians
We can use the formula for arc length:
s = rθ
where s is the arc length, r is the radius, and θ is the central angle in radians.
Plugging in the given values, we get:
51 = r(3)
Solving for r, we divide both sides by 3:
r = 17
Therefore, the radius of the circle is 17 cm.
