Respuesta :

perimeter or rectangle= 2l+2w

Surface area of a cylinder=2(pi)r^2+2(pi)r

Volume of a triangular prism=Bh

Area of a circle=(pi)r^2
Bh - volume of triangular prism
2πr²+2πrh - total surface area of cylinder
πr² - area of circle
2l+2w - area of rectangle.

you literally need to study this. because this is nothing in math (yet everything)
