V = (pi)r^2 * h
V / (pi)r^2 = h
V = 904.78
r = 6
904.78 / (3.14 * 6^2) = h
904.78 / (3.14 * 36) = h
904.78 / 113.04 = h
8.004 rounds to 8 = h........height is 8 cm

Answer:
Ginny made a mistake in step 1 when she identified b = 31. It should be b=-31
Step-by-step explanation:
Ginny factored
as shown:
ac = –180 and
b = 31
36(–5) = –180 and 36 + (–5) = 31
+ 36x – 5x – 30
6x(x + 6) – 5(x + 6)
(x + 6)(6x – 5)
b is the coefficient of x and from the trinomial
, b=-31.
Therefore Ginny made a mistake in step 1 when she identified b = 31. It should be b = –31.
The correct steps are:
:
ac = –180 and
b = -31
36(–5) = –180 and -36+5 = -31


3 is correct , base is never equal to 1 cause all of solves of logarithm will be 0
