Answer:
The radius is 19.42 inches.
Step-by-step explanation:
Start with the formula for finding the circumference of a circle, which is C=2r.
Then, derive the formula in order to find the radius, which the formula should then look like r= C/2.
Finally, plug in the corresponding numbers, which is r= 122 inches/ 2. The final answer is 19.42 inches.
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 = is used to convert it. So:
θ =
θ =
S = rθ
25 = r
900 = 7r
r =
r = 40.925556... cm
