Webwhich lets us find the circumference C C of any circle as long as we know the diameter d d. Using the formula C = \pi d C = π d Let's find the circumference of the following circle: 10 10 The diameter is 10 10, so we can plug d = 10 d = 10 into the formula C = \pi d C = πd: C = \pi d C = πd C = \pi \cdot 10 C = π ⋅ 10 C = 10\pi C = 10π That's it! WebIf your aspect ratio is (x,y) in the plane, this diagram indicates how many unit circles can fit in that rectangle. For large rectangles, you'll be best off with something approximating a …

WebWorking backwards with this formula, a rectangle that requires 25 circles of radius r would actually be a square 6r on a side; N ( r, 6 r, 6 r) = ( 6 r / 2 r + 1) ( 6 r / 2 r + 1) + ( 6 r / 2 r) ( 6 r / 2 r) = 4 2 + 3 2 = 25. Halving the radius of the circles, we'd need N ( r / 2, 6 r, 6 r) = N ( r, 12 r, 12 r) = 7 2 + 6 2 = 85. WebThe obvious square packing is optimal for 1, 4, 9, 16, 25, and 36 circles (the six smallest square numbers ), but ceases to be optimal for larger squares from 49 onwards.
