well density measures how much an object is by its size and you calculate it by finding the mass then volume.Then you divide the two answers then whatever answer you get,you round it to the nearest tenths
Circle is geometrical figure it is made by using compass box and round is shape of circle there is no need of compass box to made up round
Any theory which involves things orbiting round a central object. Such as the early theory of atomic structure.
it depends how you accurate you want it, or how precise (they are different things) you could say -0.7 or you could say -1
Exactly 40+10+40+10 = 100cm which is its perimeter
It is the distance that covers round a shape or object.

Solid objects do not have a perimeter because it is not possible to go all round the object in a single path.
That is called the perimeter; in the case of round shapes such as circles or ellipses, it is usually known as the circumference.
Not sure how the perimeter of a solid object is defined. It cannot be a path around all the edges since even with a simple polyhedron - a cube - there is no route that does not require retracing or repeating an edge. Is it the sum of the edges' lengths? And would the definition extend to polyhedra in higher dimensions? A round shape - in 2-dimensions - does have a perimeter.
The distance round a closed figure is the perimeter.
Two methods: 1. mark a point on the circumference of the round object; put a mark on the floor; line up the marks and roll the object along the floor until the mark retouches the floor; use the meter rule to find the distance between the marks on the floor. 2. measure the diameter of the round object using the meter rule and multiply it by π (pi ≈ 3.14159)
Calipers can measure the diameter of round objects by using the outside jaws for external measurements and the inside jaws for internal measurements. By measuring the distance across the round object with the jaws, the caliper can provide an accurate reading of its size.
Its called a perimeter, cause a perimeter is the outside, so it must be a perimeter! :)
its a big circle
If the distance round the circle is 5.14 units then the distance round 1/2 of it would be 2.57 units.
Perimeter of a round plate = 2*pi*radius or pi*diameter
