Area of <span>parallelogram=base * height
so it is 12*9=108 yd²</span>
The idea of the Cavalieri's Principle states that even if the cylinder is oblique, so long as the planes in the figure are parallel, the equation would still be equal to,
V = Bh = πr²h
Substituting,
2,500 = π(10 m)²h
h = 7.95 m
The answer should be 5 meters.
B is the answer
Hope this help help
