Hello from MrBillDoesMath!
Answer:
1283.3
Discussion:
Volume of figure =
volume of cone + volume of cylinder =
(1/3) Pi r^2 h + Pi r^2 h =
(1/3) Pi (7)^2* 7 + Pi (7)^2 * 6 =
Pi * 7^2 ( (1/3) *7 + 6) = => using PI is approx 22/7
(22/7) * 7^2 ( 7/3 + 6) =
(22/7)* 49 (25/3) = 1283.3
Thank you,
MrB
Answer:
I believe it would be C.
Step-by-step explanation:
I believe it would be under 8 percent since 9 is lower
Your answer for your question is going to be.... um.... sorry I forgot
Answer:
First, plug-in x and y as 3sinθ-2 and 3cosθ+4 into the equation, respectively:

Then, +2 and -2 cancel out and +4 and -4 cancel out as well, leaving you with:

We can factor out 3^2 = 9 from both equations:

We know from a trigonometric identity that
, meaning we can reduce the equation to:


And therefore, we have shown that (x+2)^2 + (y-4)^2 = 9, if x=3sinθ-2 and y=3cosθ+4.
Hope this helped you.
