Question

Julia just learned how to ride a unicycle. How far did Julia cycle if the diameter of the unicycle wheel is 16 inches and she made six revolutions with the wheel without falling?

Answer 1

Julia rode a unicycle for a distance of approximately 301 inches by making six revolutions with a wheel diameter of 16 inches.

Step-by-step explanation:

The subject of the question is Mathematics, and it pertains to Middle School level. Julia rode a unicycle for a certain distance, and to calculate this distance, we need to use the formula for the circumference of a circle: Circumference = π × diameter. Since the diameter of the unicycle wheel is 16 inches, the circumference for one revolution will be π × 16 inches.

For six revolutions, the distance (X) she traveled is:

X = Circumference × Number of revolutions

X = π × 16 inches × 6

Substituting π with approximately 3.14:

X = 3.14 × 16 inches × 6

X = 301.44 inches

The rounded distance is therefore approximately 301 inches.
