Diameter of a circle.If the diameter of a circle is 1.3x10^-12 meters,then what is it's radius?

radius is half the diameter

Thank-you

To find the radius of a circle, we can divide the diameter by 2.

In this case, the diameter of the circle is given as 1.3x10^-12 meters.

To find the radius, we divide the diameter by 2:
Radius = Diameter / 2

So, substituting the given value, we have:
Radius = (1.3x10^-12) / 2

To simplify this, we divide the numerator (1.3x10^-12) by the denominator (2):
Radius = 0.65x10^-12

Since 0.65 is not in scientific notation, we can write it as 6.5x10^-13.

Therefore, the radius of the circle is 6.5x10^-13 meters.
