how is the simplest way to find the volume of a cylinder, triangle, square, circle and other 3-dimentianal shapes. if you can find a link for me too that would be great.

The simplest way to find the volume of a cylinder is 22/7×r^2×h ,triangle is 1/2×bh×hb,square is l^4,circle is 22/7r^3,and other 3 dimentianal shapes are cuboid is l×b×h,cube is l^3,sphere is 4/3×22/7×r^2

hope it is correct if not i'm srry i tried to
