The sum<span> of the measures of the interior angles of any </span>quadrilateral<span> can be found by breaking the </span>quadrilateral<span> into two triangles. Since the measure of the interior angles of any triangle equals 180 degrees, each of the two triangles will contribute 180 degrees to the total for the </span>quadrilateral<span>.</span>
Answer:
1004.8 in³
Step-by-step explanation:
d = 2r => r = d/2 = 16in/2 = 8 inches
V = Ab×h
= π·r²×h
= 3.14·(8in)²×5in
= 1004
