Answer:
d
Step-by-step explanation:
cause it is d o.49
So you do the total of the top divided by the bottom. 3411-234=3177. Now 3177/3 which = 1059
Answer:
15. y<1 16. y>or=-2 17. y>0 18. y<or=3 19. y<or=1200
Step-by-step explanation:
Answer : 12
Explanation :
In the first row of the table, we find that the -2 is the change, and in the third row -6 is the change.
Using this, we can find that the second row should have -4 subtracted from 16.
We know this because from looking at the changes from the first and second row, the differences multiply by two, as the rows increase. So -2 multiplied by 2 is -4, and 16 subtract 4 is 12.
V(cylinder)= πr²h
d=2r,
d is diameter, r is radius.
When diameter is tripled, a new diameter D=3d,
new radius R=3d/2=(3*2r)/2=3r
R=3r
V(new cylinder)= πR²h = π(3r)²h=9πr²h
V(new cylinder)/V(cylinder)=9πr²h/πr²h=9
Volume new cylinder 9 times more the volume of old cylinder.
