Question

What is the volume of cylinder with a diameter of 6 cmand a height of 11 cm?

Answer 1

V=99π cm³ (or approximately 311 cm³ rounded off to the nearest whole)

1) Let's use a formula to find out the Volume of the Cylinder:

$V=\pi\cdot r^2\cdot h$

2) SInce the Diameter has the following equivalence to Radius:

D=2R then we can state that the radius is 3 cm long.

So we can plug into that the given information:

$\begin{gathered} V=\pi\cdot r^2\cdot h \\ V=\pi\cdot(3)^2\cdot11 \\ V=99\pi cm^3 \end{gathered}$

3) Hence, the answer is V=99π cm³
