The distance around the circle would be equal to the circumference of the circle, which can be calculated using the formula:
Circumference = 2 x π x radius
Since the path across the middle is 1/2 a mile (or 0.5 miles), this would be the diameter of the circle. To find the radius, we divide the diameter by 2:
radius = 0.5 / 2 = 0.25 miles
Now, we can calculate the circumference using π ≈ 3.14:
Circumference = 2 x 3.14 x 0.25 ≈ 1.57 miles
Therefore, the distance all the way around the circle is approximately 1.6 miles.
Jamila wants to walk with her friend at the park but isn’t sure how long the course is. She knows it is a circular path with a walkway through the middle, and the path across the middle is 12 of a mile. What is the distance all the way around the circle? Give the answer to the nearest tenth of a mile.
