the radius of earth is 4000 miles, how far would you travel in going around the equator?

You're looking for the circumference of the earth.
C = pi * d
C = 3.14 * 8,000
C = ? 
i don't understand. That my homework question

Katy: what is PI*8000?

The radius of earth is 4000 miles, how far would you travel in going around the equator? I need the answer to this.

The radius is 4,000 miles, so the diameter is 8,000 miles.
Multiply: 3.14 times 8,000 to find your answer. 
thanks

You're welcome.
