So the first one is -0.5 and second is -0.5 the third one is -0.5 and the fourth is -0.25 so I would say that is D
Answer:
1. 16π
2. 112π
3. 351.68
Step-by-step explanation:
Area of a circle = πr^2
Substitute...
=4^2π
=16π
To find the how much fluid it can hold, just basically find its volume. To do that, you mutiply the area of the base by the height. So...
16π*7=122π
You then just subsitute π by 3.14 so...
122(3.14)=351.68
Answer:
the system of equation has infinite solution
Step-by-step explanation:
, 
Solve the first equation for x_2
Subtract 5x1 on both sides
Now substitute -5x1 on second equation
0=0
So the system of equation has infinite solution
Answer:
25
