For formulae, Area and Volume Formula for geometrical figures.
Specify your problem which you donít get.
Ok I have this Maths courseowrk that has to be in tomorow and i've only done the simplest parts and now i need help coz my teacher will kill me if i dont kill myself first!
Anyway, so, i need to know the formula for the area/volume of these shapes in x/y form:
Right angled triangle (shortest lengths x and y)
Square based pyramid
And then i need help with how to work out the equation e.g:
Cirlce - Area = Pi*r≤
Circumference = 2*Pi*r
2*Pi*r = Pi*r≤ (/r)(/Pi)
r = 2
Rectangle - Perimeter = 2x + 2y
Area = xy
xy = 2x + 2y (-2x)
xy - 2x = 2y
x (y - 2) = 2y (/ (y - 2))
x = 2y / y - 2
If anyone can help it would be amazing!!!
I don't know how to work through the equations eg:
So looking at the site i've been given i need to do -
2x + 2y = x * h
I have a worksheet from my teacher that tells me the answers but I dont know how to get to the answer which is x = 2y / (h - 2)
