If the diameter of a circle is 1.3 x 10-12power what is the radius?
--------------
d+=+1.3%2A10%5E-12
r is d/2
r+=+0.65%2A10%5E-12
r+=+6.5%2A10%5E-13

If the diameter of a circle is 1.3 x 10-12power what is the radius?
------------
r = (1/2)(1.3 x 10^-12)
--------------------
1.3x10-12 = 13x10-13
-----
So, r = (1/2)(13x10^-13) = 6.5x10^-13
