A cylinder has a helght of 16 cm and a radius of 5 cm. A cone has a helght of 12 cm and a radius of 4 cm. If the cone is placed
erma4kov [3.2K]

Answer:

1055.04 cm³

Step-by-step explanation:

Given that,

Height of a cylinder, h = 16 cm

Radius of the cylinder, r = 5 cm

The height of a cone, h' = 12 cm

The radius of a cone, r' = 4 cm

The volume of the cylinder will be :

V=\pi r^2 h\\\\=3.14\times 5^2\times 16\\\\=1256\ cm^3

The volume of a cone is given by :

V'=\dfrac{1}{3}\pi r^2 h\\\\=\dfrac{1}{3}\times 3.14\times (4)^2\times 12\\\\=200.96\ cm^3

Volume of the air surrounding the cone Inside the cylinder = 1256 - 200.96 = 1055.04 cm³

Hence, the required answer is equal to 1055.04 cm³.

Rita caught 5 fish. The lengths, in inches, of each tish are listed.
Aloiza [94]

Given:

The lengths, in inches, of each fish are listed:

9, 13, 9, 21, 18

To find:

The statement that best represents the meaning of the range for these data.

Solution:

The given data values are:

9, 13, 9, 21, 18

Arrange the data values in ascending order.

9, 9, 13, 18, 21

Here, the maximum value is 21 and the minimum value is 9.

We know that,

\text{Range}=\text{Maximum value}-\text{Minimum value}

\text{Range}=21-9

\text{Range}=12

The range of the data set is 12. Therefore, the difference between the shortest and longest fish is 12 inches.
