The answer is D. THe last one.
Answer:
Step-by-step explanation:
Givens
d = 3"
h = 1 inch
pi = 3.14
Formula
V = pi r^2 h
Solution
r = d/2
r = 3/2 = 1.5
V = 3.14 * 1.5^2 * 1
V = 3.14 *2.25
V = 7.065
|4x-9|=5x
subtract 4 to both sides
and that will give you
|-9|=x then the 9 turns positive because of the brackets
9=X
15
9 squared + 12 squared
i think its 1.2 not too sure though
