This interactive feature illustrates Archimedes' basic approach to calculating pi. It finds an approximation by determining the length of the perimeter of a polygon inscribed within a circle and ...
•3.7(B) - determine the perimeter of a polygon or a missing length when given perimeter and remaining side lengths in problems •4.1(A) - apply mathematics to problems arising in everyday life ...
Solving 'algebraic' problems - Eduqas Example - finding the perimeter of a rectangle Algebra problems can relate to any area of maths. Problems often include a mix of algebra, number and geometry.
Archimedes, through some further clever geometry, figured out how to estimate the perimeters for polygons with twice as many sides. He went from a 6-sided polygon, to a 12-sided polygon, to a 24 ...
Make sure you don’t miss out one side, then stop when you get back to the mark. So, the perimeter of this polygon is 36! 36 thingmys. Crow: ... For example, the area of a right angled triangle.
For example, consider a regular polygon of "radius" r, ... The area and perimeter ratios are shown and as n, the number of sides, gets larger we get a better approximation to π=3.14159 ...
