Answer:
(b) Radius of the sphere = 5 units.
Step-by-step explanation:
Here, given:
The volume of the sphere = cubic units ... (1)
Also, radius of the sphere = x units
Now, VOLUME OF SPHERE =
So, volume of a sphere with radius x =
But volume of sphere is given by (1).
Hence, radius of the sphere = 5 units.

x² - 5x = 14
x = -2 or x = 7
x² - 5x - 14 = 0
(x+2)(x-7) = 0
x=5
-2(-3+ x) = -4
Distribute
-2 * -3 + (-2) *x = -4
6 -2x = -4
Subtract 6 from each side
6 -2x-6 = -4-6
-2x = -10
Divide each side by -2
-2x/-2 = -10/-2
x = 5
