Explanation:
as with any regular 3D object : the volume is
base area × height
in the case of a cylinder, the base area is a circle, abd the area of circle is
pi × r²
with r being the radius (= half of the diameter).
so, in our case we have the volume to be
pi × (14/2)² × 8 = 3.14 × 7² × 8 = 3.14 × 49 × 8 =
= 1,230.88 mm³
