You ride your bike 42 feet. Both wheels on the bike have a diameter of 18 inches. How many complete revolutions does the front wheel make?

Answer :

The front wheel makes 9 complete revolutions.

First, we need to convert the diameter of the front wheel from inches to feet:

18 inches = 1.5 feet

The circumference of the front wheel is:

circumference = π × diameter = π × 1.5 feet ≈ 4.71 feet

To find out how many complete revolutions the front wheel makes while traveling 42 feet, we can use the following formula:

number of revolutions = distance traveled / circumference

Plugging in the values, we get:

number of revolutions = 42 feet / 4.71 feet per revolution ≈ 8.92 revolutions

Since the front wheel needs to make complete revolutions, we can round the answer to the nearest whole number:

The front wheel makes 9 complete revolutions.

To find the number of complete revolutions the bike's front wheel makes, calculate the wheel's circumference using its diameter and then divide the total distance traveled by the wheel's circumference. The front wheel makes approximately 8.91 revolutions.

To determine how many complete revolutions the front wheel of a bike makes when it has traveled 42 feet, first, we need to calculate the circumference of the wheel. The wheel's diameter is given as 18 inches. Since the circumference of a circle is (π d), where (d) is the diameter, we find the circumference:

Circumference = (π × 18 inches

Circumference = (18 × 3.14159 inches

Circumference approx. 56.55 inches

Next, we convert the total distance traveled from feet to inches for easy comparison:

42 feet \\times 12 inches/foot = 504 inches

Then we divide the total distance traveled (in inches) by the circumference of the wheel to find the number of wheel revolutions:

Number of revolutions = Total distance / Circumference

Number of revolutions = 504 inches / 56.55 inches per revolution

Number of revolutions approx. 8.91

Therefore, the front wheel makes about 8.91 complete revolutions when you ride your bike 42 feet.
