Answer: Choice D
======================================================
Explanation:
The formula for the surface area of a cylinder is
![SA = 2\pi*r^2 + 2\pi*r*h](https://tex.z-dn.net/?f=SA%20%3D%202%5Cpi%2Ar%5E2%20%2B%202%5Cpi%2Ar%2Ah)
We then replace r with 10 and h with 25. Keep in mind that the diameter is 20 mm, so the radius is half that at 10 mm.
So that's how we get to
![SA = 2\pi*10^2 + 2\pi*10*25](https://tex.z-dn.net/?f=SA%20%3D%202%5Cpi%2A10%5E2%20%2B%202%5Cpi%2A10%2A25)
The correct answer is <span>A) P'(3, −4), Q'(−3, 4), R'(6, −3)</span>
Rx = 0 indicates a reflection over the y-axis.
The rule for such a transformation is:
(x, y) --> (-x, y)
which means that the x-coordinate changes sign and the y-coordinate stays the same.
Therefore:
P<span>(-3, -4) --> P'(3, -4)
Q(3, 4) --> Q'(-3, 4)
R(-6, -3)</span> --> R'(6, -3)
These points are those in option A).
Answer:
The answer is C.
Step-by-step explanation:
Multiply 4 by 76, 77, and 78.
4 * 76 = 304
4 * 77 = 308
4 * 78 = 312
304 = 304, so C is the correct answer.
Hope this helps!
Answer:
100
Step-by-step explanation:
6 . 10^4 = 6 . 10000 = 60000
6 . 10^2 = 6 . 100 = 600
60000 ÷ 600 = 100
Point two should be your answer
