the diameter of a wheel is 63 cm, the distance travelled by the wheel in 200 revolution is :
one rotation covers 63π cm
so 200 rotations will cover .... ?
Thanks
To find the distance traveled by the wheel in 200 revolutions, we need to calculate the circumference of the wheel and then multiply it by the number of revolutions.
The circumference of a circle is given by the formula:
Circumference = π × Diameter
Given that the diameter of the wheel is 63 cm, we can substitute this value into the formula to find the circumference.
Circumference = π × 63 cm
Now we need to convert the number of revolutions (200) into the total distance traveled. Since one revolution covers the circumference of the wheel, we can simply multiply the circumference by the number of revolutions.
Distance traveled = Circumference × Number of Revolutions
Let's calculate the distance traveled by the wheel:
Circumference = π × 63 cm = 197.92 cm (rounded to two decimal places)
Distance traveled = 197.92 cm × 200 revolutions = 39,584 cm (rounded to the nearest whole number)
Therefore, the wheel travels approximately 39,584 cm in 200 revolutions.
