We have seen in the Triangle Sum<span> Conjecture that the</span>sum<span> of the </span>angles<span> in any triangle is 180 degrees. The</span>Quadrilateral Sum<span> Conjecture tells us the </span>sum<span> of the</span>angles<span> in any convex </span>quadrilateral<span> is 360 degrees. Remember that a polygon is convex if each of its</span>interior angles<span> is less that 180 degree.</span>
Answer:
V =718.0866 in^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2h
The radius is 3.3 and the height is 21
V = pi (3.3)^2 * 21
V = pi (10.89) (21)
V =pi 228.69
We can approximate pi by 3.14
V = 3.14(228.69)
V =718.0866 in^3
