Explanation: took the test
I'm sorry you need to be more clear I don't understand the question.
Volume of a cylinder = πr^2 h = π x (2)^2 x 3 = π x 4 x 3 = 12π = 37.7 cm^3
Both solutions are x<span> = 2 and x = -2 are correct
because
</span>when x = 2 , |2| = 2
and
<span>when x = -2, |-2| = 2
hope it helps</span>
