Question

Диаметр колеса велосипеда 60 см . Какое расстояние проедет велосипедист,если колесо совершит 5 оборотов?

Answer 1

0.6Х3.14Х5 равно 9.42 метра или 942 сантиметра

Answer 2

Calculating Distance Traveled by Bicycle

To calculate the distance traveled by the bicycle, we can use the formula:

Distance = Circumference of the wheel × Number of revolutions

Given that the diameter of the bicycle wheel is 60 cm, we can calculate the circumference using the formula:

Circumference = π × Diameter

Substituting the value of the diameter (60 cm) into the formula gives us:

Circumference = π × 60 cm

Now, let's calculate the circumference and then use it to find the distance traveled by the bicycle.

Calculating Circumference

The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter.

Using the given diameter of 60 cm: Circumference = π × 60 cm

Substituting the Value of π

The value of π is approximately 3.14. Substituting this value into the formula: Circumference = 3.14 × 60 cm

Calculating the Circumference

Circumference = 188.4 cm

Calculating Distance Traveled

Now that we have the circumference, we can calculate the distance traveled by the bicycle when the wheel makes 5 revolutions: Distance = Circumference × Number of Revolutions

Substituting the values: Distance = 188.4 cm × 5

Final Calculation

Distance = 942 cm

Therefore, the bicycle will travel a distance of 942 cm when the wheel makes 5 revolutions.
