Answer:

The answer to your question is 4.

Step-by-step explanation:

You take

7 and times it by 4

than you take 8 and times it by 4

Now you take both numbers

28 times by 32 to equal 896

Finally you divide your number by 2. To equal 448.

Here is the formula

Area= Base * Height / 2

:) Hope this helps

In order to overlook someone's faults, it takes love and an understanding that you are not perfect.
When you love someone, you tend not to see that person's flaws, or even if you do see them, you believe those flaws are negligible. Once you understand that you yourself are not perfect (as any other human being), it will be easier for you to overlook someone else's faults.

mash [69]

Answer:

h = A/πr²

Step-by-step explanation:

Surface area (A) of a cylinder = πr² × height (h) , where r is the radius.

h = A ÷ πr² = A/πr²

Answer:

Answer is option d)346.4 ft

Step-by-step explanation:

$from \: the \: figure \\ AB = 300 \: ft \: \: \: angle \: C = 60 \:( theta)\: degress \\ in \: triangle \: ABC \: using \: tan \: theta\\ \tan(60) = \frac{opposite \: side}{adjacent \: side} \\ \tan(60) = \frac{300}{BC} \\ \sqrt{3} = \frac{300}{BC} \\ BC = \frac{300}{ \sqrt{3} } \\ BC = 100 \sqrt{3} ft \\ then \: in \: triangle \: ABD \: using \: tan \: theta \\ angle \: D = 30 \: degrees \: (theta) \\ \tan(30 ) =\frac{opposite \: side}{adjacent \: side} \\ \tan(30) = \frac{300}{BD} \\ \frac{1}{ \sqrt{ 3} } = \frac{300}{BD} \\ BD = 300 \sqrt{3} \\ CD = BD - BC \\ = 300 \sqrt{3 } - 100 \sqrt{3} \\ = (300 - 100) \sqrt{3} \\ = 200 \sqrt{3 } \\ = 200 \times 1.732 \\ = 346.4 \: ft$
