Hello,
very simple they intercept supplementary arcs. (making a sum of 360°/2 for inscribed angles )
If you use the formula V=bh you can find the volume of a tranangular prism.
To find the area of the triangle you have to use the formula A=1/2bh
A=1/2(14)(20)=140ft2= Base of the triangle
V=bh V=140x30
V=4200ft2
