the surface area of the sphere is π/4 cm^3
<h3>How to determine the surface area</h3>It is important to know the formula for surface area and volume of a sphere
Surface area =
Volume =
First, let's determine the value of radius, r
The value for volume was given as 256/3π cm3.
Pi cancels out and we have cross multiply to get the radius
Make r the subject of the formula
r = 4
Let's substitute to find the surface area
Surface area =
Surface area = π/4
Surface area = π/4 cm^3
Thus, the surface area of the sphere is π/4 cm^3

Answer:
The inequality for the given graph is .
Step-by-step explanation:
From the given graph it noticed that the line passing through (0,-1) and (3,1).
The equation of line passing through two points is defined as
The equation of line is
Therefore the related equation is .
The point (0,0) lies in the shaded region, therefore the point (0,0) is the solution of required inequality.
Put (0,0) in the related equation.
Since 0 is greater than -1, therefore the sign of inequality must be >. The related line is a dotted line, therefore we cannot use .
Therefore the required inequality is
