Answer:
22,000 miles
Skills required: Geometry
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
----> When given the radius, the circumference is equal to:
(or
)
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:
--->
(doing
yields the answer of
).
Both of these answers are around 22,000 miles.
