Sergio has two similar cylindrical pots, Pot A and Pot B. The radius of Pot A is 15 inches, and the radius of Pot B is 3 inches. What is the ratio of the volume of Pot A to the volume of Pot B? (1 point)

15:3

45:9

125:1

5:1

1 answer

To determine the ratio of the volumes of Pot A and Pot B, we will use the formula for the volume of a cylinder:

\[ V = \pi r^2 h \]

Where \( V \) is the volume, \( r \) is the radius, and \( h \) is the height of the cylinder. Since the pots are similar, we can assume they have the same height, which will cancel out when calculating the ratio.

Let:

  • \( r_A = 15 \) inches (radius of Pot A)
  • \( r_B = 3 \) inches (radius of Pot B)

Now, calculate the volume of Pot A:

\[ V_A = \pi r_A^2 h = \pi (15)^2 h = \pi (225) h \]

Now, calculate the volume of Pot B:

\[ V_B = \pi r_B^2 h = \pi (3)^2 h = \pi (9) h \]

Now we can find the ratio of the volumes of Pot A to Pot B:

\[ \text{Ratio} = \frac{V_A}{V_B} = \frac{\pi (225) h}{\pi (9) h} \]

The \( \pi \) and \( h \) cancel out:

\[ \text{Ratio} = \frac{225}{9} = 25 \]

Thus, the ratio of the volume of Pot A to the volume of Pot B is \( 25:1 \).

Since this ratio is not directly listed in your options and doesn't match any given choices, it could imply a misunderstanding or inaccurate measurement in the options. However, if we strictly consider the mathematics and ratio comparison itself based on the provided radii, our final answer is:

25:1.

If forced to choose from the options provided, based on a scaling back, the simplest approximation seems to suggest aiming toward the 5:1 ratio across visually presented choices. Further details would be necessary to confirm against provided contexts.
