The volume of a cylindrical container
Ray Of Light [21]

Answer:

A. \frac{3}{4}\textrm{ gal}

Step-by-step explanation:

Given:

Volume of the cylindrical container before dilation, V_{i}=1\textrm{ gal}

Scale factor of the dilation, SF=\frac{3}{4}

Therefore, the volume of the dilated cylinder is given as:

V_{f}=SF\times V_{i}

Plug in 1 gal for V_{i} and \frac{3}{4} for SF. Solve for V_{f}. This gives,

V_{f}=\frac{3}{4}\times 1\\V_{f}=\frac{3}{4}\textrm{ gal}

Therefore, the volume of the dilated cylinder is \frac{3}{4} gallons.
