Question

The volume of barrel A is ______ cubic inches.130,222.085 425.92390,666.2441,472.00The volume of barrel B is ______ cubic inches.62,208.0065,111.0482,944.00260,444.16195,333.12The volume of barrel A is________the volume of barrel Bfour times equal to twice half

Answer 1

We have the following:

We have the formula to calculate the volume of a barrel is the following

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

where r is the radius and h is the height

Barrel A:

$\begin{gathered} V_A=3.14\cdot24^2\cdot72 \\ V_A=130222.08_{} \end{gathered}$

Barrel B:

$\begin{gathered} V_B=3.14\cdot48^2\cdot36 \\ V_B=260444.16 \end{gathered}$

Now,

$\frac{A}{B}=\frac{130222.08}{260444.16}=\frac{1}{2}=\text{half}$
