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

$\frac{4}{3}\pi r^{3}$

(r=radius)

so let's just plug in what we know

4/3(pi)(10)^3

we can calculate this with a calculator to get 4188.8 cm^3.
