Answer:
The height of the cylinder is 4x units.
Step-by-step explanation:
volume of a cylinder = nr^2h
n = 22/7
r = radius = x/2
Let illustrate with an example. If the diameter of a cylinder is 6 and the volume is 6^3 = 216. The radius = 6/2 = 3
n3^2 x h = 216
h = 216/9 = 24
so the height is 4 times the diameter
Area of the base = nr^2
1/2^2 x x = 1/4 pi x^2
Substitute y = -2x + 4 into 7y = -14x +28
7y = -14x +28
7(-2x + 4)= -14x +28
-14x + 28 = -14x +28
0 = 0

Answer:
71
Step-by-step explanation:
This is the answer because:
1) First, add Andy's score and Janet's score in order to know how much they got in total:
- Janet's score: 119 + 96 + 145 = 360
- Andy's score: 127 + 74 + 88 = 289
2) In order to find how much more Janet scored, jus subtract Andy's score from Janet's score:
Therefore, the answer is 71.
Hope this helps! :)
