If The Diameter Of A Circle Is

1.3 X 10^-12 Meters, Then What Is Its Radius?
Can you give me step by step. I think I want to divide this by 2 but I am not sure how to do that.

Would it be this:

1.3/2*10^-12=
.65*10^-12=
6.5*10^13

your exponent should have been -13, probably just a silly typo.

I make those all the time
Reiny,

Yes, I meant to write -13, so it was my typo. But thank you for looking.
