Final answer:
The unicycle's wheel with a diameter of 50.8 cm turned 5 times completely, covering a total distance of 7.98 meters when rounded off to two decimal places.
Step-by-step explanation:
The question asks to calculate the total distance traveled by Jake's unicycle's wheel, which has a diameter of 50.8 cm and turns 5 times completely.
To find the distance, we first calculate the circumference of the wheel, which is the distance traveled in one complete turn, using the formula C = πd, where C stands for circumference, π is Pi (approximately 3.14), and d represents the diameter. After obtaining the circumference, we multiply it by the number of turns to get the total distance traveled.
First, we find the circumference:
C = πd
= 3.14 × 50.8 cm
= 159.512 cm.
Next, multiply the circumference by the number of turns:
Total distance = 5 × 159.512 cm
= 797.56 cm.
Finally, to convert centimeters to meters, divide by 100:
Total distance in meters = 797.56 cm / 100
= 7.9756 meters, which, rounded off to two decimal places, is 7.98 meters.
