the formulae are different for different shapes, you have to be more speciefic.
No such formula exists. The diameter of a circle is a linear measure, square measure are for areas.
To convert square millimeters (mm^2) to square centimeters (cm^2), divide the area in square millimeters by 100. This is because there are 100 square millimeters in a square centimeter. Formula: cm^2 = mm^2 / 100.
A 50mm circle has a diameter of 50 millimeters, which is approximately 1.97 inches. The radius, which is half the diameter, measures 25 millimeters (about 0.98 inches). To find the area, you can use the formula A = πr², resulting in an area of approximately 1,963.5 square millimeters.
There are 100 square millimeters in a square centimeter. This is because a square centimeter is 10 millimeters by 10 millimeters, giving a total of 100 square millimeters.
It depends very much on what the question is!
The perimeter of a square with a diagonal length of 24 square root 2 millimeters (33.94 mm) is: 96 mm
Millimeters are fractions of a meter. There are 1000 mm in 1m. The easiest way to find the number of meters in a given quantity of millimeters is to divide by 1000. Since square measures are made by multiplying lengths and widths, 1 square meter (1mx1m) is equal to 1,000,000 square millimeters (1000mmx1000mm.) To find a number of square meters in an area of square millimeters, you can divide the given area by 1million. For example: A square with sides measuring 123mm has an area of 15129mm^2. Dividing that number by 1million converts it to 0.015129m^2
134 square millimeters
One square centimeter is 100 square millimeters.
1.5 million square millimeters
5 square millimeters is 0.01 square inches.
Since each meter has 1000 millimeters, each square meter has a million square millimeters.
