a circular track has a radius of 100ft. elena wants to run 2 miles. There are 5,280 ft in a mile.
Can you find the circumference of a circle if you know the radius? explain your answer
Circumference, C = 2 pi r
or, C = pi d
C = 2 pi r
C = 2(3.24)(100)
C = 628 feet for one lap
5280 * 2 miles = 10,560 feet
10560/628 = ? = laps in 2 mile
Yes! To find the circumference of a circle, we use the formula:
Circumference = 2 * π * radius
Here, the radius of the circular track is given as 100ft. So, let's substitute the value into the formula:
Circumference = 2 * π * 100ft
Now, we know that π (pi) is approximately equal to 3.14159. Therefore, we can simplify the equation further:
Circumference = 2 * 3.14159 * 100ft
Circumference = 6.28318 * 100ft
Circumference = 628.318ft
So, the circumference of the circular track is approximately 628.318 feet.
