The wheel in the figure has a diameter of 1 yard. The wheel is rolled forward as shown until the point marked A has undergone exactly one revolution around the wheel's axis. What number is represented by the distance in yards that the wheel has traveled along the ground? PLEASE HELP
C = pi * d
C = 3.14 * 1
C = 3.14 yards
thank you Ms. Sue u always are ready to help other people
You're very welcome. :-)
To find the distance the wheel has traveled along the ground, we need to determine the circumference of the wheel. The circumference of a circle can be calculated using the formula:
Circumference = π * Diameter
Given that the diameter of the wheel is 1 yard, we can substitute this value into the formula to find the circumference:
Circumference = π * 1 yard
Since we don't have the exact value of π, we can use an approximation, such as 3.14, to estimate the circumference:
Circumference ≈ 3.14 * 1 yard
Therefore, the approximate circumference of the wheel is 3.14 yards.
Now, since Point A undergoes exactly one revolution around the wheel's axis, we know that Point A would travel a distance equal to the circumference of the wheel. So, the distance represented by the movement of Point A along the ground would also be the same as the circumference of the wheel, which is approximately 3.14 yards.
