OpenStudy (anonymous):

ooh u do this: C=2 pie (3.14) r (Radius) for example 50000 is 3.14x10^5 because there are 5 digits in the number and solve

I don't follow

let me make it easier, so the circumference of the earth is 24,901 miles. 24,901 is 3.14 (u always use this number to find circumference) 3.14x10^5 (the ^ is to the power so ^5 is 10x10x10x10x10 5 times) But sometimes, we round it up to 25,000 so it would be 3.14x10^5=25,000 did u get that?
