Answer

Explanation:

Step1: Calculate volume of cylinder

The formula for the volume of a cylinder is $V=\pi r^{2}h$. Given $r = 0.3$ m, $h=0.75$ m and $\pi = 3.14$. So $V=3.14\times(0.3)^{2}\times0.75$. $V = 3.14\times0.09\times0.75=0.21195$ $m^{3}$.

Step2: Calculate mass of kerosene

The formula for mass is $m=\rho V$, where $\rho$ is density and $V$ is volume. Given $\rho = 815$ kg/$m^{3}$ and $V = 0.21195$ $m^{3}$. So $m=815\times0.21195$. $m = 172.73925\approx173$ kg.
