If the radius of a circle is 13 inches what is the diameter?
The diameter of any circle is twice its radius. A circle with a radius of 13 inches will have 2 x 13 = 26 inches for a diameter.
What is the lenghth of a diameter of a circle with the radius of 13 centimeters?
The diameter of a circle is always twice the length of the radius. Therefore, if the radius is 13 centimeters, the diameter would be 2 x 13 = 26 centimeters.
What is the circumference of a circle if the radius is 13?
2 x 13 x pi = 81.68 Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 2*pi*13 = 81.68140899
How do know how to make out circumference and diameter if you only know the radius?
If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)
What is diameter in terms of radius?
diameter = 2 x radius
How do you calulate radius into diametre?
the radius is one-half the diameter radius = diameter/2 diameter = 2 x radius
What is the diameter if radius is 7.4?
diameter = radius x 2 = 7.4 x 2 = 14.8
How do you work out tha area of a circle?
Assuming you know the radius or diameter...(Pi) x (radius) x (radius) or (1/4 Pi) x (diameter) x (diameter) will give you the area.
How do you get circumference when you are given radius?
Circumference is equal to pi x diameter Diameter is equal to 2 times the radius Circumference would be 2 x pi x radius
Does the area of a circle treble if the diameter trebles?
No. The area of a circle is 3.142 x radius x radius (radius is half the diameter).
What circumference equals radius 8?
Circumference = (pi) x (diameter) Diameter = 2 x radius
How many gold atoms are there in a sphere that is 13 in diameter?
I will use the volume of a sphere formula and the density of gold to find this answer. The radius of gold is 144 picometers. 13 inches (2.54 centimeters/1 in)(1 meter/100 centimeters)(1012 picometers/1 meter) = 3.30 X 1011 picometers --------------------------------/2 = 1.65 X 1011 picometers in radius of this sphere =================================So, that means that the radius of the gold would be as to the sphere..., 1.65 X 1011 picometers/144 picometers = 1.15 X 109 picometers of gold radius here =======================================================( final answer )
