The answer is C, because when isolating the variable it is not important to start with a specific one, either way will give you the correct answer
Hi, I have an answer for you, hope is O.K.
Answer:
<em>Area = 254.34 inches ³</em>
Step-by-step explanation:
The formula to find the surface area of a sphere is:

To find the volume of the sphere, we first need to figure out the radius (
) of the sphere. We can accomplish this by reversing the formula that was used to find the surface area. 


Divide both sides by pi (
).


Divide both sides by 4.


Find the square root of both sides.


<em>radius = 9</em>
<em />
Insert the value of the radius into the formula for finding the volume of a sphere. 




<em>Area = 254.34 inches ³</em>
