Answer:

Equation for the area of a circle- π r²

The 2 radiuses are 6 and 9.

6 squared is 36 and 9 squared is 81.

The smaller one is 36π and the larger one is 81π.

The difference between them is the area of the shaded region.

81π - 36π = 45π

Use 3.14 for π.

45 x 3.14 = 141.3 u²

Hope this helps!

A pizza is cut into twelve pieces. Describe the steps you would take to find the area of one slice of the pizza.
DanielleElmas [232]
Hey there!

First, you would need to find the area of the circle/pizza . . .

Formula of finding area → pi*r²  (Pi * the radius of the circle/pizza²)
---
Once you have found the area, you would need to divide the result by the number 12 since there is a total of 12 slices in the pizza.
---
This is how you would find the area of one slice of pizza.
