They are seperate from each other that said,none of each other's business:)
The ratio of three squares to five circles can be expressed as 3:5. This means for every three squares, there are five circles. The ratio shows the relative quantities of the two shapes compared to each other.
The answer depends on what information you have about the circles and their relative positions. If you have the radii of the two circles, r and s, and the distance between their centres, d then the two circles can be written as:(x + d/2)2 + y2 = r2 and (x - d/2)2 + y2 = s2.=> 2xd = r2 - s2=> x = (r2 - s2)/2d where all three values on the right hand side are known. So, x can be calculated and, substituting this value of x in the equation for either circle gives a quadratic equation in y. Solving the quadratic will give y1 and y2. Then the coordinates of the chord's end-points are (x, y1) and (x, y2) and the length of the chord is abs(y2 - y1).
Any number from 2 to 10, depending on their relative shapes, sizes and positions.
A cylinder has two circles as its bases.
