What does the ∩ symbol represent in math?
2 answers:
"∩" is called the union symbol. It's commonly used in engineering. The intersection of sets ‘A’ and ‘B’ is the set containing the unique elements from both set ‘A’ and set ‘B’. Thus, to create an intersection, elements found in both original sets, which are the duplicates discarded by the union operation.

Answer:
h = 21.5cm.
Step-by-step explanation:
<em>Step one:</em> Simplify the volume.
220.16 x (pi) = 691.65cm^3.
<em>Step two:</em> Isolate h.
Cylinder volume equation: V = (pi)(r^2)(h), where r is the radius and h is the height.
Divide out the pi and r^2 on both sides to isolate h and move the equation to V/(pi)(r^2) = h.
<em>Step three:</em> Solve for h.
691.65/(pi)(3.2^2) = 21.5cm rounded to the nearest tenths place.
