Question

СРОЧНО ОТДАМ ВСЕ БАЛЛЫ!!!;!!!!Колесо на расстоянии 285 м сделало 120 оборотов. Найди диаметр колеса .Ответ округли до десятых

Answer 1

длина окружности С = 2πR = πD (D - диаметр)

285 : 120 = 2.375m - один оборот колеса он же длина окружности C

π ≈ 3.14

2.375 = 3.14 * D

D = 0.7563694 ≈ 0.8 m

Answer 2

Calculation of Wheel Diameter

To find the diameter of the wheel, we can use the formula:

Circumference = π * Diameter

Given that the wheel has made 120 revolutions and traveled a distance of 285 meters, we can calculate the circumference of the wheel:

Circumference = Distance / Number of Revolutions

Circumference = 285 m / 120 = 2.375 m

Now, we can use the formula for circumference to find the diameter:

Diameter = Circumference / π

Diameter = 2.375 m / 3.14159 ≈ 0.756 m

Rounding to the nearest tenth, the diameter of the wheel is approximately 0.8 meters.

Please let me know if there's anything else I can help#### Calculation of Wheel Diameter

To find the diameter of the wheel, we can use the formula:

Circumference of the wheel = Diameter of the wheel × Number of revolutions

Given that the wheel made 120 revolutions and covered a distance of 285 meters, we can calculate the circumference of the wheel:

Circumference of the wheel = Distance covered / Number of revolutions

Let's substitute the given values into the formula:

Circumference of the wheel = 285 meters / 120 revolutions

Simplifying the equation:

Circumference of the wheel = 2.375 meters per revolution

Now, we can find the diameter of the wheel by rearranging the formula:

Diameter of the wheel = Circumference of the wheel / π

Since we are asked to round the answer to the nearest tenth, we can use an approximation of π as 3.14.

Diameter of the wheel = 2.375 meters per revolution / 3.14

Calculating the result:

Diameter of the wheel ≈ 0.756 meters (rounded to the nearest tenth)

Therefore, the diameter of the wheel is approximately 0.8 meters.
