WebbPerimeter = 30 cm ; Circles. Finding the perimeter of a circle can be tricky! We need to remember that a circle is still a two dimensional shape with an outside edge that we can measure. We know that a circle only has one edge – all around the outside. We use a special word for the perimeter of a circle – it is called the circumference.
Webb7 dec. 2012 · The simplest method would be to generate a random angle θ ∈ [ 0, 2 π]. Then convert from polar to Cartesian with ( x, y) = ( r cos θ, r sin θ). Note that if your random number generator returns a number k ∈ [ 0, 1] then θ = 2 π k.
