a diameter of a car wheel is 49cm.find how many turns will it take to cover a distance of 3080cm
First you need to get circumference of wheel which is 49*2*pi=98pi
then u divide 3080 to 98 pi and u will get 10.0(3sf) -that means the wheel is rotated on that distance 10 times
To find out how many turns it will take for the car wheel to cover a distance of 3080 cm, we need to calculate the circumference of the wheel first.
The circumference of a circle can be found using the formula: circumference = π * diameter
Given that the diameter of the car wheel is 49 cm, we can substitute this value into the formula:
Circumference = π * 49 cm
To find the number of turns, we need to divide the total distance (3080 cm) by the circumference of the wheel.
Number of Turns = Total Distance / Circumference
Now, we can calculate the number of turns:
Number of Turns = 3080 cm / (π * 49 cm)
To get a numerical value, we'll use the approximation value of π, which is approximately 3.14.
Number of Turns = 3080 cm / (3.14 * 49 cm)
Calculating this, we find:
Number of Turns ≈ 19.74
Therefore, it will take approximately 19.74 turns for the car wheel to cover a distance of 3080 cm.
