Determine the volume of the figure. Use 3.14 for π. Round your answer to the nearest tenth. Show all of your work.

Ostrovityanka [42]

Answer:

1985 cubic units (written as un. with the cubed exponent)

Step-by-step explanation:

First, you find the volume of the cylinder

Here's the formula:

$V=\pi r^{2}h\\V=volume\\r=radius\\h=height$

Now, you plug in and solve.

$V=(3.14)(7.2^{2})(7.4)\\V=(3.14)(51.84)(7.4)\\V=(162.7776)(7.4)\\V=1204.55424\\rounded:\\V=1204.6$

Then, you find the volume of the dome.

Here's the formula:

$volume/of/a/sphere=\frac{4}{3}\pi r^{3}\\volume/of/a/dome:\\V=\frac{2}{3}\pi r^{3} \\V=volume\\r=radius$

Now, you just plug in and solve.

$V=(\frac{2}{3})(\pi)(r^{3})\\V=(\frac{2}{3})(3.14)(7.2^{3})\\V=(\frac{2}{3})(3.14)(373.248)\\V=(2.093)(373.248)\\V=781.208064\\rounded:\\V=781.2$

Finally, you add them together, and there's your answer!

$1204.6+781.2=1985.8$

Hope this helped!

Explain why a graphical display might be skewed. How do you ensure data isn’t skewed?

Leno4ka [110]

Sample Response: If the data is collected in a biased manner, the graph could be skewed. Also, if the number of observations is too small, the graph can be skewed. To ensure the data is not skewed, collect a large representative unbiased sample

The largest of the Great Pyramids in Egypt was built with a square base, having edges that measured 754 feet and a height of 418

12345 [234]

Answer:

79,213,229 ft3

Step-by-step explanation:

The volume of a pyramid is given by the following formula:

Volume = (1/3) * B * h

Where B is the base area and h is the height.

The side of the base is 754 feet, so the base area is:

B = 754^2 = 568516 ft2

Then, the volume of the pyramid is:

Volume = (1/3) * 568516 * 418 = 79213229.33 ft3

Rounding to the nearest cubic foot, we have:

Volume = 79,213,229 ft3
