Pi Day Question

[LaxGirl]

I need some help figuring out these questions for Pi Day:
#1. If Juan can consume in one sitting one medium (12 inch diameter) deep dish (1 inch thick) pizza, what is the minimum volume of his stomach?

#2 What is the area of the union of two circles of radius 1 whose centers are 1 unit apart?

#3 If a circular track is 5 meters wide and it takes a horse, traveling its fastest, pi more seconds to travel the outer edge than the inner edge, what is the horse's speed?

I need some help What kind of help do you need on each of these?

Your request for help is too vague for me to determine what you're missing.

Please make some statements about what you already know or tried. Or, ask some specific questions.

The author of the first exercise implies that ingestion does not alter food volume and that "empty" stomachs contain nothing, but that implication is ignorant of human physiology and anatomy.

?So, I suggest that you ignore the scenario presented in the first exercise. They just want the volume (in cubic inches) of a cylinder of diameter 12 inches and height 1 inch.

Have you used the famous formula for the volume of a cylinder, before?

Exercises 2 and 3 look like fun. I can think of different ways to solve them.

What have you learned in class, so far, about circles and their areas and circumferences? What have you thought or done, to begin making an effort on these exercises?
