This is the complete question

Ana's younger brother and sister went on a carnival ride that has two separate circular tracks. Ana's brother rode in a blue car that travels a total distance of 220 feet around the track. Ana's sister rode in a green car that travels a total distance of 126 feet around the track. Ana drew a sketch of the ride.

Are the distances of 220 feet and 126 feet the radii, diameters, or circumferences of the two circles? Explain

Step-by-step explanation:

Given two circular track

Length of the track 1 is 220ft

Length of the track 2 is 126ft

Explanation

The circumference of a circle is also called the perimeter of a circle.

Perimeter of a plane shape is the sum of all the lengths of the plane shape.

So, The perimeter or circumstances of a circle is total length of the circle.

Now, given that the total length of track 1 is 220ft, this implies that the circumference of the circle is 220ft

P1 = 220ft

Also, for track 2, since the length is 126ft, then, the circumference of the second track is 126ft.

P2 = 126ft

To calculate the diameter of each track.

The circumference of a circle can be determined using the formula

P = πd

Where d is diameter and P is perimeter or circumference of the circle

Then,

d = P /π

So, for track 1

d1 = P1 / π

d1 = 220 / π

d1 = 70.03 ft.

For track 2

d2 = P2 / π

d2 = 126 / π

d2 = 40.11 ft.

So, the radius of a circle can be determined from the diameter

Radius. = diameter / 2

So,

For track 1

r1 = d1 / 2

r1 = 220 / π /2

r1 = 110 / π

r1 = 35.01 ft

Also, for track 2

r2 = d2 / 2

r2 = 126 / π / 2

r2 = 63 / π

r2 = 20.05 ft

The difference between the two track radius is

∆r = r1 - r2

∆r = 110 / π - 63 / π

∆r = (110 - 63) / π

∆r = 47 / π

∆r = 14.96 ft.

∆r ≈ 15 ft

The difference between the radii of the two circular tracks is approximately 15ft
