Squares do not have diameters; circles have them. If you are referring to the diagonal of a square, then you would use Pythagorean's Theorem to determine the length of the diagonal. 'Square' the length of one side and multiply by 2, then take the square root of that number to get the length of the diagonal.
that is = under root( 2 s) where s= side
If the circle inscribes the square, the diameter equals the square's side length. In this case, 16mm.
Subtract the square of the width from the diameter. The square root of that is the length.
If the circle touches each edge of the square then its diameter is the same as the side of the square and its circumference is pi times the diameter.
Diameter implies circle Divide diameter by two square it. Multiply it by pi (3.14159...)
The same as half the side of the square, as the radius of the circle is half its diameter, and the diameter of the circle is equal to the side of the square.
half the diameter and then get the radius times pi and square it
The area of a circle with a diameter of 6 units is: 28.27 square units.
radius = diameter/2 area of a circle in square units = pi*radius2
If you have the diameter, then the formula for the area of a semi-circle is:(pi x (diameter/2)2)/2That is,Divide the diameter in two to find the radius (diameter/2)Square the radius (radius x radius)Multiply it by pi (3.1416)Divide the answer by two to find half the circle.Remember your units. The answer will be in square inches, or square centimeters or square somethings.
Divide the diameter by 2 to get the radius then square the radius, and finally multiply by pie (3.14)
diameter = 30 units area = 225*pi square units
Divide the diameter by 2 to get the radius then square the radius, and finally multiply by pie (3.14)
