Answer:
50.265m^3
Step-by-step explanation:
because the formula for solving this problem is πr^2•height and then to finish solving it would have to be put into cubed as it's 3d
Answer:
None
Step-by-step explanation:
Let’s graph the points first.
Look at the image below.
And by looking at the image we can tell that none of the points lay on the same horizontal line.
<em>Thus,</em>
<em>none of the points lay on the same horizontal line.</em>

Answer:
7 inches
Step-by-step explanation:
you divide 50 into 150 and then you get 3.5. then you take 3.5 and times it by 2 to get 7.
Answer:
3^3 x 3.14
9 x 3.14 = 28.26
28.26 x 2 = 56.52
2 x 3.14 x 3 = 18.84
18.84 x 10 = 188.4
Now lets add all given areas:
56.52 + 188.4 = 244.92 m^2 for question 1
4 x 3.14 x 12^2
4 x 3.14 x 144 = 1,808.64 cm^2 is your answer for question 2
14^2 x 3.14
196 x 3.14 = 615.44
3.14 x 14 x 33 = 1450.68
1450.68 + 615.44 = 2,066.12 cm^2 is your answer for question 3 I think
