Question | Answer |
Regular polygons are | Convex, equilateral, equiangular |
Every regular polygons is | cyclic |
The perimeter of a regular polygon depends on two things: | The radius, the number of sides |
perimeter of a regular polygon | 2nrsin(180/n) |
Area of a triangle= | 1/2(rsqrt3/2)(r/2) |
Area of a regular polygon | nr^2sin(180/n)cos(180/n) |
Circumference of a circle= | 2rπ |
Circumference of a circle also= | dπ |
Area of a circle= | πr^2 |
A sector is | bounded by two radii and an arc |
Area of a sector= | x/360πr^2 |
Arc length= | x/360(2)πr |
