Imagine 4 circles just touching, like this OO
.............................................................. OO only closer.
Draw a square connecting the centres of the 4 circles.
Given the circles each have a radius of 10 metres the length of each side of the square
is (10+10) =20 metres and the area of the square is 400 square metres.
The area of each quarter of the circle that is within the square is
one quarter of pi times r squared so the four quarters = 100pi square metres
so the space between the circles is the difference.

What is the formula for finding the surface area of the wall of a cylinder?
Divided into 3 sections (the rounded middle-section and the two circular ends), the surface afrea is equal to the area of the circular end multiplied by two (which equals pi X the radius of the circle squared) plus the circumference of the circular end multiplied by the length of the cylinder. Therefore total surface area = 2(pi X radius squared) + length(pi X 2 X radius)

How do you calculate armoured cable cross-sectional area?
For electrical purposes the formula for calculating the circular-mil area of a circular wire is very simple. A = D squared, Area equals diameter of the cable or wire squared. This calculation is needed when pulling cables into a cable tray so as not to overfill the tray. Over filling a cable tray will build up a heat from the cables if proper ventilation between the cables is not maintained.
