Answer:
1260 rotations
Explanation:
From the question given above, the following data were obtained:
Diameter of tyre = 16 in
Number of rotation =?
Next, we shall determine the radius of the tyre. This can be obtained as follow:
Diameter (d) of tyre = 16 in
Radius (r) of tyre =?
r = d / 2
r = 16/2
Radius (r) = 8 in
Next, we shall determine the circumference of the tyre. This can be obtained as follow:
Radius (r) of tyre = 8 in
Pi (π) = 22/7
Circumference (C) of tyre =?
C = 2πr
C = 2 × 22/7 × 8
C = 50.29 m
Finally, we shall determine the number of rotation. This can be obtained as follow:
Circumference (C) of tyre = 50.29 m
Number of rotation (n) =?
n = 63360 / C
n = 63360 / 50.29
n = 1260 rotations
Therefore, the tyre will make 1260 rotations
