One of the simple joys of life is a push-pop candy. You remember ‘em:

Right, a lollipop without a stick.

And while it sounds like a push-up, a Push-Pop doesn’t have the same effect.

(And no, eating one does not have the same effect as doing an actual push-up).

Back when I was a kid, I always wondered how much good stuff was in a tube. Thanks to the wonders of a simple math formula to calculate **the volume of a cylinder**, we can solve this burning question! It isn’t quite the same as calculating the volume of a cone, but it’s still feasible.

CAVEAT: (Ideally, the candy went all the way to the bottom of the tube, but we kids knew this was never the case. ☹)

Here’s the** formula for the volume of a cylinder**:

Hmmmm, this may look familiar to some of you. Here’s why:

This is a cylinder. It’s basically a tube that has the *same width at every point*. When you look at the end points, they are perfect circles.We know the formula for finding the **area** inside of a circle, right? If that doesn’t ring a bell, it might be a good idea to get some equations homework help.* r* is simply the *radius*, or a straight line from the edge of the circle to the center.

Once we find out **the area of a circle**, we just extend it into a third dimension, which is the *height*. *Multiplying the area by the height gives us the volume*!

Let’s go back to our push-up candy!

Let’s assume I haven’t eaten it already.

Mine looks to be about 1.75 cm across and 4.5 cm tall. Yeah, they’re not as big as they used to be.

Here’s the formula: *V = Πr ^{2}h *

Make sense? If not, this would be a good time to message an online math tutor. Since we know the *diameter i*s 1.75 centimeters per pop, we can simply *cut the number in half to get the radius.*

1.75 ÷ 2 = 0.875 centimeters

Now, plug in the numbers:

V = Πr^{2}h*
*V = Π0.875

^{2}x 4.5

V = Π0.765625 x 4.5

V = Π x 3.4453125

V = 3.14 x 3.4453125

V = 10.82 cm

^{3}

Don’t forget the little 3 after the label. We are calculating in *three dimensions.*

*Hurrah for the volume master! Time for a treat!*
