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
