Hello!

$\large\boxed{V = 471cu ft}$

Find the volume of the cylinder using the formula:

$V = h(\pi r^{2})$

We are given the diameter, so solve for the radius:

$d = 2r\\\\10 = 2r\\\\r = 5 ft$

Use the given height and radius to solve for the volume:

$V = 6(5^{2}\pi )\\V = 6 * 25\pi \\\\V = 471 cu ft$

answer:

the answer to question 1 is a.

the answer to question 2 is d.

it is d because a[tex](1\frac{1}{3})[/tex] is a greater number than b[tex](-\frac{1}{2})[/tex] and b[tex](-\frac{1}{2})[/tex] is a greater number than c(-2).

hope this !

A = 77.32

Step-by-step explanation:

Since this is a right triangle we can use trigonometric functions

sin = opposite side/ hypotenuse

sin A = 80/82

sin A =40/41

Take the inverse sin of each side

sin^-1 (sin A ) =sin ^-1 (40/41)

A =77.31961651

Rounding to the nearest hundredth

A = 77.32

x=150°

Step-by-step explanation:

Using the vertical angle theorem, you can infer that AEC and DEB are in fact the same angle, 20°, and the same goes for FED and CEG, both 130°.

So, x spans AEC and CEG so is 20° + 130° = 150°

21. Smith received 60% of the votes
Murphy received 1/3 or 33%
100% - (60% + 33%) = 100 - 93 = 7%so where is the other 7% of the votes. The vote total should equal 100%

22. Food : 500/2000 reduces to 1/4or 25%or 0.25
Rent : 1200/2000 reduces to 3/5or 60% ...or 0.6
Transportation : 300/2000 reduces to 3/20...or 15%..or 0.15

23. sum of the rows:
Food + rent + trans = 1/4 + 3/5 + 3/20 = 5/20 + 12/20 + 3/20 = 20/20 = 1
Food + rent + trans = 25% + 60% + 15% = 100%
Food + rent + trans = 0.25 + 0.6 + 0.15 = 1
The sums should all equal because the percent, decimals, and fractions are all the same, just in a different form

24. 14.5% = 0.145 = 145/1000 = 29/200
14.5 = 14.5 = 14 1/2 = 29/2
14.5% is less then 1
14.5 is greater then 1
