Hello!
The equation for find the h when given volume and radius is

h is height
v is volume
r is radius
Put in the values you know

Since there is pi on the top and bottom we can get rid of it
multiply the 3 by the top number

the answer is 8m
Hope this helps!
Answer:
Step-by-step explanation:
x² + 4x -21 = x² + 7x - 3x -3*7
= x*(x + 7) -3(x + 7)
=(x + 7)*(x-3)
X - 3 < -9 x + 5 > = 12
x < - 9 + 3 x > = 12 - 5
x < - 6 x > = 7
open circle on -6, shaded to the left.....closed circle on 7, shaded to the right
