Answer:
25.13 in^2.
Step-by-step explanation:
I will assume a circular pizza with 8 pie shaped pieces.
Each of the 8 sectors is one piece of pizza. So find the area of the the circle, radius = 16/2 = 8, that is π * 8^2 and divide by 8 getting 8π for the area of each slice. Note: 8π ≈ 8 * 3.1416 ≈ 25.13 in^2.

i solved it
Michael bought 7 pizzas from Pizza by Alfredo and 9 pizzas from Alfredo's Pizza Cafe.
Step-by-step explanation:
Cost of Pizza at Pizza by Alfredo = $3
Cost of pizza at Alfredo's pizza cafe = $5
Total amount spent = $66
Let,
Pizzas bought from Pizza by Alfredo = x
Pizzas bought from Alfredo's Pizza Cafe = y
According to given statement;
3x+5y=66 Eqn 1
5y = 3x+24 Eqn 2
Putting value of 5y from Eqn 2 in Eqn 1;

Dividing both sides by 6

Putting x=7 in Eqn 2

Dividing both sides by 5

Michael bought 7 pizzas from Pizza by Alfredo and 9 pizzas from Alfredo's Pizza Cafe.
