Answer:
6075π ft^3
Step-by-step explanation:
The formula for a cylinder is πr^2 * h
were:
h = height
and r = radius
and because the radius is always 1/2 of the diameter, the radius is 22.5.
So now we plug everything in:
π*22.5^2 * 12
= π*506.25 * 12 =
π * 6075 =
6075π
please don't forget to add the units.
answer;
C.21 you have to subtract each number.
Answer:
372000
Step-by-step explanation:
You multiplay 1000x372 and this the answer
Answer: You would tell him 1,425ft².
Step-by-step explanation:
f
First, you need to know the equation for finding the area of a trapezoid, which is <em><u>½</u></em><em><u>h</u></em><em><u>(</u></em><em><u>b1</u></em><em><u>+</u></em><em><u>b2</u></em><em><u>)</u></em> .
When you plug in all the number you have into the equation, you have a new equation essentially that says, <em><u>½×30(65+50)</u></em> .
When you start solving the equation, you need to do parentheses first, so <em><u>65+30</u></em>, which would get you 95. This would then turn the equation into <em><u>½×30(95)</u></em> .
Next, you have to do <em><u>30×95</u></em>, which would come out to be 2850. When you do this, your equation would now be <em><u>½</u></em><em><u>×</u></em><em><u>2</u></em><em><u>8</u></em><em><u>5</u></em><em><u>0</u></em> , or essentially <em><u>2850</u></em><em><u>÷</u></em><em><u>2</u></em> .
When you do the last and final step of the problem, which is <em><u>½×2850</u></em>, you would get 1425. But since it's area, your answer would <em><u>1425ft²</u></em>.
Answer:
6x-24y
Step-by-step explanation:
Step 1: -30x-12y+36x-12y
Distribute-3 to 10x and 4y
Then distribute 6 to 6x and -2y
Step 2: 6x-24y
After that add up like terms
