In order to solve for this, we need to find the volumes of both the cylinder and cone described.

In order to find the area of the cylinder:
We use the equation V=\pi r^{2} h
So, V=\pi 6^{2}16
The volume of the cylinder is therefore approximately <span>1809.56m^{3}

For the cone:
V=\pi r^{2} \frac{h}{3}
So, V=\pi 6^{2} \frac{3}{3}
Thus, the volume of the cone is 113.1m^{3}

We add these volumes together to derive the solution, which is 1922.66m^{3}</span>

An online test of English spelling looked at how well people spelled difficult words. The bar graph to the right shows how many
sweet-ann [11.9K]

Answer:

60 ; 5220

Step-by-step explanation:

A) From the horizontal bar chart provided, it could be inferred that 85 people spell the word 'weird' correctly. The graph is scaled on a fixed interval of 10. Hence, the midpoint of 10 = 5

(80 + 5) = 85

B) In a group consisting of 8719 randomly selected people estimate how many more people can correctly spell weird than inoculate

From the graph :

85 per 100 could spell weird correctly while,

About 25 per 100 could spell inoculate correctly.

Difference In number per 100 people

(85 - 25) = 60 people per 100

We could round 8719 to the nearest 100 = 8700

Number of 100's in 8700 = 8700/100 = 87

(87 × 60) = 5,220 people

Which is larger 2/3" x 3-7/16" or 0.6"L x 3.43"W?
Darina [25.2K]
2/3 x (3 - 7/16) = (2/3) * (3+7/16)
       = (2/3)*(55/16)
       = 55/24
       = 2.2917

0.6 x 3.43
      = 2.058

The first answer is greater than the second.

Answer:  2/3 x 3-7/16 is larger.
