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 radius is half of the diameter. So if it is 13 cm, the diameter must be 26 cm.
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 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 )
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
