The answer will be 62.4. We know this because of the next procedure:
<span>We know that:
the volume of a cylinder is pi * r^2 * h
the volume of a cone is 1/3 * pi * r^2 * h
the total height is 47.
the height of the cone is 12.
</span><span>the height of the cylinder must be 35.
Now, if the top half is filled with sand, then the volume of the sand is
pi * 4^2 * 36 and the volume of the cone is 1/3 * pi * 4^2 * 12.
the total volume = 1960.353816 cubic millimeters.
since the top drains at the rate of 10 * pi cubic millimeters per second, the top will be empty and the bottom full after 1960.353816 / (10 * pi) = 62.4 seconds.
I hope this answer is ok for you </span>
Answer:
r = 0.16
Step-by-step explanation:
C = 2·π·r
1 = 2·π·r
1/2 = π·r
0.5 = π·r
0.5 / 3.14 = r
0.16 = r
I believe it is a 2/25 probability that a Virgina senator will get chosen.
You do this by dividing 50 by 2 then since there is two senators for every state you make it 2 out of 25.

Áp dụng tính chất của đường trung bình ta có:
20+x=2.(2x+22)
20+x=4x+44
X-4.x=44-20
-3.x=24
X=24/-3x=-8
Trong độ dài ko có độ âm nên tất cả đại lượng hình học đều mang dấu (+) vì vậy kết quả cuối cùng sẽ là 8
