Step-by-step explanation:
X f(x)
---- -------------------------------
-2 4(1/2)⁻² = 4.[1/(1/2)²] = 16
-1 4(1/2)⁻¹ = 4.[1/(1/2)¹] = 8
0 4(1/2)⁰ = 4(1) =4 & so on & so forth
The volume of a sphere is given by the equation

, where r is the radius.
We are given the diameter of the sphere, but recall that the diameter is twice the radius:

. So the radius is half of the diameter:

.
Half of 8 cm is 4 cm.
We substitute this for r in the equation and we use 3.14 for <span>π.</span>
