Answer:
The distance that the toy tire moves after 12 rotations is 188.4 cm
Step-by-step explanation:
The distance that a circular shape can move in n rotation is D = πdn, where
- d is the diameter of the circular item
- n is the number of rotation
∵ A toy tire has a diameter of 5 cm
∴ d = 5 cm
∵ The toy tire moves 12 full rotations
∴ n = 12
→ To find the distance that the toy tire moves use the rule above
∵ D = (π)(5)(12)
∵ π = 3.14
∴ D = 188.4 cm
∴ The distance that the toy tire moves after 12 rotation is 188.4 cm
