- Perimeter of a circle as a limit of inscribed regular sided polygon
Canada Discussion Starter Sep 9, 2024 #1 Show that the perimeter Pn of an n-sided regular polygon inscribed in a circle of radius r is P n = 2 n r sin (π n) Find the limit of Pn as n approaches ∞ My attempt: The sum of the interior angles is π (n − 2) If we apply the cosine law to find the length of each side of the n-sided regular

- Area as a function of width - Math Help Forum
Hi Holly, let's make the example a little easier to helpl you understand Let's say we only had one sheep pen fenced by 500 feet Calling the length L and the width W then it makes sense that the total perimeter of the fence is 2 L + 2 W = 500 We know the area of a rectangle is A = L × W so looking back at the first equation and solving for L we get 2 L + 2 W = 500 2 L = 500 2 W L = 250 W
