One vase has a height of 2 and a radius of 2, and the other has a height of 6 and a radius of 1, so which one has more volume

1 answer

To find out which vase has a greater volume, we can use the formula for the volume \( V \) of a cylinder, which is given by:

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

where \( r \) is the radius and \( h \) is the height.

For the first vase:

  • Height (\( h_1 \)) = 2
  • Radius (\( r_1 \)) = 2

The volume \( V_1 \) is calculated as follows:

\[ V_1 = \pi (r_1^2)(h_1) = \pi (2^2)(2) = \pi (4)(2) = 8\pi \]

For the second vase:

  • Height (\( h_2 \)) = 6
  • Radius (\( r_2 \)) = 1

The volume \( V_2 \) is calculated as follows:

\[ V_2 = \pi (r_2^2)(h_2) = \pi (1^2)(6) = \pi (1)(6) = 6\pi \]

Now we can compare the two volumes:

  • Volume of the first vase: \( 8\pi \)
  • Volume of the second vase: \( 6\pi \)

Since \( 8\pi > 6\pi \), the first vase has a greater volume.

Thus, the first vase (height = 2, radius = 2) has more volume than the second vase (height = 6, radius = 1).
