i have a globe & want to find out the diameter.i thought it was the measurement of all the way around but that's the circumference.

the circumference is 1000mm

Circumference of a circle formula
C = π d
C / π = d . . . Use this formula
- - - - - -
Measure the circumference of the globe.
divide that measurement by π and the results is the diameter
- - - - - -s-

the diameter is a line that goes right through the centre inside the globe.like from north pole to south pole
u could measure the circumference then draw a circle with the same circumference on a piece of paper.mark the centre of the circle and use a ruler to measure the width of the circle

Simple sollution to a sinple question:
Diameter = Circumference / π
For the sake of ease π=3.14159265
ie If the circumference = 45cms the the diameter equals
45cms / 3.14159265 or approx 14.325cms
Hope this helps.

If you know the circumference you can work out the diameter. Circumference = pie * Diameter
Therefore: Diameter =Circumference/Pie
Pie = 3.142
Diameter = Circumference divided by 3.142

The diameter is used in measuring 2D circles. It is the length of a line drawn from one side of the circle, through the centre point, to the other side.

Divide the circumference by 3.142

circumference = pi x diameter
so your globe has a diameter of 318.268mm

This is difficult with a 3d object, I think there's a calculation for it, but I couldn't tell you! If the circle was 2d it would be the measurement from one side to the other.

Diameter is the width at the widest part

since C=πd then d=C/π
if you can find the circumference, simply divide by pi!
