calculusxy · Answer

The formula for finding the volume of a cylinder is:
$$V = Base \times height$$

$$Base$$ represents the area of the circle (which is the base): $$\pi \times r^2$$

So here you have:
$$(\pi \times r^2) \times height$$

33?

calculusxy · Answer

Wait, I am just going to calculate it.

calculusxy · Answer

How did you get 33?

anonymous · Answer

h=v/pie*r^2

anonymous · Answer

it told me not to use 3.12 as pi

calculusxy · Answer

Pi is 3.14 not 3.12. So what number are you using for pi, or are you using the symbol on the calculator?

anonymous · Answer

thats what i meant. sorry. i was using the symbol on the calculator. the question said 33 was right.

calculusxy · Answer
