Math 182 Miniproject 4 The Volume of a Football
===

**Overview:** In this project we find exact formulas for integral approximations using Riemann sums of various flavors.

**Prerequisites:** Section 6.2 of _Active Calculus_.

Go to https://www.desmos.com/calculator/c7aip1g33m to see a regulation size football image. (All units are inches.) 

1. Using your graph plotting kung fu, find a curve that approximates the boundary of (at least part of) the football.
$$-0.1053411x^2+3.4$$

2. Set up an integral expression that will give the volume of the football.
$$2\int_{0}^{5.69}\left(-0.1053411x^{2}+3.4\right)^{2}\pi dx$$



3. Use Desmos to find the value of your integral. What is the volume of the football?
$$220.07817in^3$$
