## anonymous one year ago George bought a new graduated cylinder for his chemistry class. It holds 728.97 milliliters of liquid. If the cylinder has a radius of 4.7 cm, then how tall is the cylinder? (1 milliliter is equal to 1 cubic centimeter) 155.1 cm 24,056.01 cm 77.55 cm 33 cm i need help asap

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?

3. calculusxy

Wait, I am just going to calculate it.

4. calculusxy

How did you get 33?

5. anonymous

h=v/pie*r^2

6. anonymous

it told me not to use 3.12 as pi

7. calculusxy

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

8. anonymous

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

9. calculusxy

Okay great!!! As long as you are correct :)
