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.

To find the radius of a circle given its diameter, you need to divide the diameter value by 2. Here's how you can solve it step by step:

Step 1: Start with the given diameter value of 1.3 x 10^-12 meters.
Step 2: Divide the diameter by 2. So, (1.3 x 10^-12) / 2 = 0.65 x 10^-12 meters.
Step 3: Simplify the result. In scientific notation, 0.65 x 10^-12 can be written as 6.5 x 10^-13 meters.

Therefore, the radius of the circle with a diameter of 1.3 x 10^-12 meters is 6.5 x 10^-13 meters.
