7%, 13%, 0.15, 4/25, 21/100, 0.28
The formula for the volume of a cylinder is:

r is the length of the radius and h is the height. Plug in the given values:

To the nearest hundredth, the volume is 28.27 in³.
16.48 probably cuz the 4 is not a 5 but check
X+8>14
Subtract 8 from both sides-
x>6
Do you need help with the graphing part too?
