Question

Steve bought a new graduated cylinder for his chemistry class. It holds 1,000 mL of liquid. If the cylinder has a radius of 5 cm, then how tall is the cylinder?
(1 milliliter is equal to 1 cubic centimeter)
A.
100 cm
B.
40,000 cm
C.
200 cm
D.
40 cm

Answer 1

B if you think about it it’s not in the hundred nor tens so b

Answer 2

The equation for volume is ‘area of the base * height = volume’
We are given the radius of the cylinder, so we can solve for the base area:
pi(r^2)
pi(5cm^2)
25cm^2(pi)
=78.54cm^2

With this, we can now use the volume formula to solve for the height. (Replace mL with cm^3)
78.54cm^2(height)=1000cm^3
Height=12.73cm

Final answer = 12.73cm
