Answer:
-6
Step-by-step explanation:
if you set m to -6, you get -10 which is less than -6
if you set m to -4, you get -6 which is equal to -6
if you set m to -2, you get -2 which is greater than -6
Answer:
16pi cm^2, 112pi cm^3, 351.68 cm^3
Step-by-step explanation:
Given: Height=7cm, radius=4cm
1. The base is a circle and Area of circle = pi * r^2
Plug in the radius to get --> A = pi * (4cm)^2 = 16*pi cm^2
2. This is asking for the volume of the cylinder.
Volume of cylinder is V=h*pi*r^2 --> 7cm * pi * (4cm)^2 = 112 pi cm^3
3. Just plug 3.14 into pi --> 112 * pi cm^3 = 351.68 cm^3
Answer:
Step-by-step explanation:

I don’t really get your question, because you said that ¾ of them are girls, Then how many girls are working in the piano?
You did not stated the question well.
However, I will try to answer this base on my understanding.
There are a total of 12 students that works in the library.
IF ¾ of them are girls:
=> 12 / 4 = 3 *3 = 9
=> 9 of them are girls and 3 of them are boys.
Thus, how many girls are working in the piano.
The probability is 9, there might be 9 girls working in the piano, or less than 9. Since you did not mention how many girls worked in different part of the library.
