A unicycle travels 50 feet. If the radius of the tire is 24 INCHES, how many times does the tire rotate?
C = pi * d
C = 3.14 * 48
C = 150.72 inches
150.72 inches = 12.56 feet
50 / 12.56 = ________ times
To find out how many times the tire rotates, we need to determine the circumference of the tire and then divide the distance traveled by the circumference of the tire.
The circumference of a circle can be calculated using the formula:
C = 2πr, where C is the circumference, π is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle.
In this case, the radius of the tire is given as 24 INCHES. Let's convert it to feet by dividing by 12 since there are 12 inches in a foot:
24 INCHES / 12 = 2 FEET.
Now we can calculate the circumference of the tire:
C = 2πr = 2 × 3.14159 × 2 = 12.56636 FEET.
Finally, we can find out how many times the tire rotates by dividing the distance traveled (50 feet) by the circumference of the tire (12.56636 feet):
50 feet ÷ 12.56636 feet = 3.979.
Therefore, the tire rotates approximately 3.979 times.
