Question

Alexis has a cylindrical trash can with a diameter of 24 cm and a height of 42 cm. What is the approximate volume of the trash can?A.1,008 cm3B.3,167 cm3C.19,000 cm3D.76,000 cm3

Answer 1

The volume of a cylinder is:

diameter= 24cm

r= d/2

radius= 24/2

radius= 12cm

height= 42cm

$\begin{gathered} V=\text{ }\pi r^2h \\ V=\text{ }\pi(12)^2(42) \\ V=\text{ }\pi(144)(42) \\ V=\text{ }\pi6048 \\ V=\text{ 19,000.35 cm}^3 \end{gathered}$

The approximate volume of the trash can is C.

$\approx\text{ 19,000 cm}^3$
