Answer:
ft³
Step-by-step explanation:
First, let's figure out how to get the <em>volume </em>of a sphere from its <em>surface area</em>. If r is the radius of our sphere, then
The formula for a sphere's surface area is
The formula for a sphere's volume is 
So to get from area to volume, we have to <em>divide the area by 3 </em>and then <em>multiply it by r.</em> Mathematically:

Before we solve for V though, we need to find the radius of our sphere. Thankfully, we're given the surface area -
ft² - so we can use the area formula to find that radius:

And now that we have our radius, we can put it into our volume formula to find
ft³
X^3 -2x^2 -35x
=x(x^2-2x-35)
=x(x-7)(x+5)
Answer is c 3 because it is multiplied 3 everytime
Answer:
144
Step-by-step explanation:
54+90=144
144-90=54
90+54=144
144-54=90
