A bicycle wheel has a small pebble embedded in its tread. The bike is set upside down, and the rider accidentally bumps the whee

nikdorinn [45]

Answer:

a) The radius of the wheel is 1) more than 25.0 cm.

b) The radius of the wheel is approximately 40.925556... cm

Step-by-step explanation:

S = rθ is the formula to find the radius of the wheel using the arc and the angle discovered, S being the arc and θ the angle. The angle, however, must be in radians. θ = $\frac{35\pi}{180}$ is used to convert it. So:

θ = $\frac{35\pi}{180}$

θ = $\frac{7\pi}{36}$

S = rθ

25 = r $\frac{7\pi}{36}$

900 = 7 $\pi$ r

r = $\frac{900}{7\pi }$

r = 40.925556... cm
