How would you find the surface area of a regular 36 sided polygon with a perimeter of 360 cm in two different ways?
The regular 36 sided polygon will have 36 equal sides of 10 cm.
All triangles have 3 sides.
It will have 36 isosceles triangles that have 2 equal sides.
Its triangles will have an apex angle of 10 degrees and 2 equal angles of 85 degrees.
The sine rule is: a/sinA = b/sinB = c/sinC
Using the sine rule its equal sides are: 57.36856623 cm.
Its area is: 0.5*57.36856623 squared *sin(10)*36 = 10,287.04707 square cm.
Alternatively its area is: 0.5*57.36856623*10*sin(85)*36 = 10,287.04707 square cm.
What else can I help you with?
What is the formula for surface area if the only measurement you have is the perimeter?
There can be no such formula in general. A formula will exist if the area is a regular polygon (or a circle).
Does a regular tessellation use four different regular polygons to cover a surface?
No, a regular tessellation uses multiple copies of only one regular polygon.
What are faces of a congruent regular polygon?
A regular polygon has equal sides and angles. A polygon has a surface area but a polyhedron has many faces as for example a pyramid.
A tessellation is a tessellation which uses only one regular polygon to cover a surface completely?

A regular tessellation is a tessellation which uses only one regular to cover a surface completely?
true.. and polygon
Which type of tessellation uses one type of regular polygon to cover a surface completely?
It is a regular tessellation.
What are some examples of geometry formulas?
There are different types of geometry formulas such as polygon properties, area formulas, volume formulas, surface area formulas, circle formulas, and perimeter formulas.
What type of tessellation uses one type of regular polygon to cover a surface completely?
If it also covers a surface without overlap, then it is a regular tessellation.
How do you find the surface area of a regular pyramid?
Surface Area= 1/2perimeter x slant height + B * * * * * Perimeter = perimeter of base. B = Area of base.
How many times do you have to run around 5 acres to be a mile?

How do you find the Surface area of pyramids?
The surface area of a pyramid is the area of all the faces of the pyramid, for a pyramid with apex in the centre and a regular polygon as its base, (the bottom of a pyramid is the base, it is regular if all sides are the same length) the surface area is: B + 1/2(P * H) where B is the area of the base, P is the perimeter (area around) the base and H is the height of the pyramid.
