Answer:
The area of the pizza crust is 200.96 inches²
Explanation:
* Lets explain how to solve the problem
- The area of any circle is πr² , where r is the length of its radius
- The length of the diameter of any circle is twice the length of
its radius (diameter = 2 radius)
* Lets solve the problem
- Alex is making a pizza
- The round pizza pan has a 16 inch diameter
- To find the area of the pizza crust is needed to fill the entire pan,
calculate the area of the pan
∵ The diameter of the pan is 16 inches
∵ The radius of the pan = 1/2 diameter
∴ The radius of the pan = 1/2 (16) = 8 inches
∵ The area of the pan = πr²
∵ π = 3.14 and r = 8 inches
∴ The area pf the pan = 3.14 (8)² = 200.96 inches²
∵ The area of the pizza pan = the area of the pizza crust
∴ The area of the pizza crust is 200.96 inches²
