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 = \sqrt[3]{\frac{768}{12} }](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B768%7D%7B12%7D%20%7D)
![r = \sqrt[3]{64}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B64%7D)
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:
up and down is y and x is side to side
On both sides of the equal sign you subtract b (-b) which would give you -b+y=2x after that you subtract a y (-y) which gives you -b=2x-y now I was taught that you can't have a negative letter equal something so you change all of the signs to the opposite which would give you b=-2x+y
