Dana is planning to ride her bicycle around the circular race track and wants to know the distance. If the diameter of the track is 2 mile, how far is the distance around the race track?
3.14(2) = 6.28 miles
correct
To find the distance around a circular race track, you need to calculate the circumference of the circle. The circumference is equal to the diameter times pi (π).
Given that the diameter of the track is 2 miles, we can calculate the distance using the formula:
Circumference = Diameter × π
Substituting the values:
Circumference = 2 miles × π
Using the approximate value of π as 3.14:
Circumference ≈ 2 miles × 3.14
Circumference ≈ 6.28 miles
So, the distance around the race track is approximately 6.28 miles.
To calculate the distance around the circular race track, we need to find the circumference of the circle. The circumference is the distance around the circle.
The formula to calculate the circumference is C = πd, where C is the circumference, π is a mathematical constant (approximately equal to 3.14), and d is the diameter of the circle.
In this case, the diameter of the track is given as 2 miles. Therefore, we can substitute the value of d into the formula:
C = 3.14(2)
C = 6.28
So, the distance around the race track is 6.28 miles.
