It's 1/2 of the diameter.
dia = 1.3E-2 = 13E-3
r = 6.5E-3 or
6.5%2A10%5E-3

If the diameter of a circle is 1.3 x 10 negative 2, what is its radius?

Radius is one-half the diameter

1.3%2A10%5E%28-2%29%2F2=0.65%2A10%5E%28-2%29=6.5%2A10%5E%28-3%29

Radius is 6.5%2A10%5E%28-3%29

I hope the above steps were helpful.
