Pizza Area and Radius Problems

The video tutorial covers application type problems, focusing on calculating the area of pizzas eaten by Dan and Charlie. Dan ate a whole pizza with a radius of 6 inches, and the area is calculated using the formula pi*r^2. Charlie ate half a pizza with a diameter of 20 inches, and the area is calculated similarly, but halved. The tutorial demonstrates how to apply mathematical formulas to real-world problems.

What is the first step in solving the pizza problem involving Dan?

• Find the circumference of the pizza

• Estimate the number of slices

• Determine the diameter of the pizza

• Calculate the area of the pizza
