Answer:
The volume of a cylinder is given by the equation:
V = π(R)^^2*h
where π = 3.14, R is the radius and h is the height.
If in the image we see that the radius is 7, then the correct option is D.
If in the image we shee that the DIAMETER is 7 (a linea that goes from end to end of the circle and goes trough the middle) then we know that the radus is half of the diameter, 7/2 = 3.5
in this case he correct option is C.

Answer:
0.92
Step-by-step explanation:
The highest rainfall was 1.25
The lowest rainfall was 0.33
1.25-0.33=0.92
In 1 hour, Hannah will play 6 2/5 songs, or 32/5.
To get from 5/8 to 1, you have to multiply by the number 1 3/5 (5/8 • 1 3/5 = 1). So, you multiply 4 by 1 3/5 too. (4 • 1 3/5) This gets you to the final answer, 6 2/5.
Ni : Zn: Cu = 7:2:9 =7x : 2x : 9x
7x+2x+9x = 3.8
18x=3.8
x=3.8/18=1.9/9≈0.21
Ni: 7x=7*0.21=1.47 ≈1.5 kg
Zn: 2x=2*0.21=0.42≈0.4 kg
Cu: 9x=9*0.21=1.89 ≈1.9 kg
Check 1.5+0.4+1.9 =3.8 True
