Question

The earth has a diameter of 7926.41 miles. What is the circumference of the earth. (this would be the distance you have to walk, if you could walk around the equator.

Answer 1

Hello from MrBillDoesMath!

Answer:

24901.6 miles    (approximately)

Discussion:

Circumference of a circle = C

= 2 Pi r

= (2r) Pi                 => as diameter = 2 * radius, so d = 25

=(7926.41)*Pi         => as Pi is approximately 3.141

=(7926.41)(3.141)

= 24901.6    (approximately)

That's a long way to walk!

Thank you,

MrB
