Hello from MrBillDoesMath!
Answer:
452
Discussion:
The volume of a cylinder of height "h" and radius "r" is given by the formula (Pi *r^2) * h. As the diameter of a circle is twice the radius, this formula is equivalent to
Volume = Pi * (d/2)^2 * h
= Pi * (8/2)^2 * 9
= Pi * 4^2 * 9
= Pi 16 * 9
= Pi * 144
Using the approximation 3.14 for Pi,
Volume = (3.14) * 144 = 452.2
The Question asks for an answer rounded to a whole number, so the answer becomes 452
Thank you,
MrB
