Answer:
22,000 miles
Skills required: Geometry
Step-by-step explanation:
1) First, we need to understand what circumference is.
- In the problem shown, we are given the radius. This is a line from the center of the circle to the edge of the circle.
- Here the radius is [tex]3500[/tex]
----> When given the radius, the circumference is equal to:
[tex]2\pi r[/tex] (or [tex]2*\pi*r[/tex])
[tex]\pi[/tex] is known as pi and is 3.14 when rounded.
(There are infinite digits to pi)
2) We can plug in for radius and using this formula:
---> [tex]2*\pi*r=2*\pi*3500=21991.15[/tex]
(doing [tex]2*3.14*3500[/tex] yields the answer of [tex]21980[/tex]).
Both of these answers are around 22,000 miles.
