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.
