Answer:
x = ±3/2
Step-by-step explanation:
4x^2 - 9=0
Add 9 to each side
4x^2 -9+9 =0+9
4x^2 =9
Divide each side by 4
4x^2/4 = 9/4
x^2 = 9/4
Take the square root of each side
sqrt(x^2) = ±sqrt(9/4)
x = ±sqrt(9)/sqrt(4)
x = ±3/2

Hello,
Using V = (pi)(r)^2(h) :
V = 12
r = ?
h = 8
12 = (pi)(r)^2(8)
12/(8pi) = r^2
sqrt(12/8pi) = sqrt(r^2)
r = .69 in
Good luck to you!
