Question

find how many turns it will take milla to travel 30m if the diamtere of her wheel is 20cm

Answer 1

To find how many turns it will take for Milla to travel 30m, we need to calculate the circumference of her wheel and then divide the total distance by the circumference.

The formula to calculate the circumference is:
Circumference = π * diameter

Given that the diameter of Milla's wheel is 20cm, we can substitute this value into the formula to find the circumference:
Circumference = π * 20cm

Using the approximate value of π as 3.14159, the circumference is:
Circumference = 3.14159 * 20cm
Circumference ≈ 62.8318cm

Now we can calculate how many turns it will take for Milla to travel 30m:
Total turns = Total distance / Circumference

Given that the total distance is 30m and the circumference is approximately 62.8318cm, we can substitute these values into the formula:
Total turns = 30m / 62.8318cm

To have consistent units, we need to convert 30m to centimeters:
30m = 30 * 100cm
30m = 3000cm

Now we can substitute this value into the formula:
Total turns = 3000cm / 62.8318cm
Total turns ≈ 47.7314

Therefore, it will take approximately 47.7314 turns for Milla to travel 30m.
