Question

диаметр колеса тепловоза равен 100 см за 2 минуты колесо сделало 400 оборотов сколько метров проходит тепловоз за минуту​

Answer 1

Ответ:

Пошаговое объяснение:

Найдем длину колеса ; С=πd = 3,14 * 100= 314 см = 3,14м

3,14 * 400= 1256 м столько колесо прошло за 2 минуты

1256 : 2= 628 м/мин столько метров в минуту проходит тепловоз

Answer 2

Ответ:

С=πd=3,14*100=314 (см)=3,14 (м) - длина колеса.

3,14*400=1256 (м) - колесо прошло за две минуты.

1256:2=628 (м/мин) -  проходит тепловоз.

Answer 3

Calculating the Distance Traveled by the Locomotive

To calculate the distance traveled by the locomotive per minute, we can use the formula:

Distance = Circumference of the wheel × Number of revolutions

Given: - Diameter of the wheel = 100 cm - Number of revolutions in 2 minutes = 400

Calculation

1. Circumference of the wheel: - The circumference of the wheel can be calculated using the formula: Circumference = π × Diameter - Substituting the given diameter: Circumference = π × 100 cm Circumference = 100π cm

2. Distance traveled in 2 minutes: - Using the formula: Distance = Circumference × Number of revolutions - Substituting the values: Distance = 100π cm × 400 Distance = 40000π cm

3. Distance traveled in 1 minute: - Since the distance for 2 minutes is known, we can find the distance for 1 minute by dividing the distance for 2 minutes by 2: Distance for 1 minute = 40000π cm / 2 Distance for 1 minute = 20000π cm

Answer

The locomotive travels approximately 20000π cm in one minute.
