Answer:
8
Step-by-step explanation:
Take the total, 50.35, and subtract 19.95:
50.35 - 19.95 = 30.40
Now divide 30.40 by 3.80:
(30.4)/(3.8) = 8
Therefore, Tony bought 8 markers.
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
