You can put this solution on YOUR website! The diameter of a circle is 1.3x10 raised to negative 12 meters. What is its radius?
------------------
D = 1.3*10^-12, or 1.3E-12
1.3E-12 = 13E-13 move the decimal one, and change the exponent one.
The radius is half the diameter.
r = 6.5E-13, or 6.5*10^-13 meters
