Question
One of the concrete pillars that support a house is $2.2 \mathrm{m}$ tall and has a radius of $0.50 \mathrm{m}$. The density of concrete is about $2.2 \times 10^{3} \mathrm{kg} / \mathrm{m}^{3} .$ Find the weight of this pillar in pounds $(1 \mathrm{N}=0.2248 \mathrm{lb})$
Step 1
The volume $V$ of a cylinder is given by the formula $V = \pi r^2 h$, where $r$ is the radius and $h$ is the height. Substituting the given values, we get \[V = \pi (0.50 \, \text{m})^2 (2.2 \, \text{m})\] Show more…
