A circular racetrack has a diameter of 200 meters. What is the approximate distance a car travels in meters for three full revolutions around the track? use 3.14 for pie.
C = pi * d
Multiply the circumference by 3.
C=d*pi= 200*pi= 200*3.14= 628 meters
To find the approximate distance a car travels for three full revolutions around the circular racetrack, we need to calculate the circumference of the track and then multiply it by three.
The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter.
Given that the diameter of the circular racetrack is 200 meters, we can substitute this value into the formula:
C = πd
C = 3.14 × 200
C ≈ 628.4 meters
So, the approximate circumference of the racetrack is 628.4 meters.
To find the distance traveled for three full revolutions, we multiply the circumference by three:
Distance for three full revolutions = 3 × 628.4
Distance for three full revolutions ≈ 1885.2 meters
Therefore, the approximate distance a car travels for three full revolutions around the track is approximately 1885.2 meters.
