PLEASE HELP ME!!
A pizza parlor offers pizzas with diameters of 6 in., 8 in., and 10 in. Find the area of each size pizza. Use 3.14 for π. Round each area to the nearest tenth, and each cost to three decimal places. If the pizzas cost $9, $12, and $18 respectively, which is the better buy?
The area of the 6-in pizza is about in2, and costs $ per in2.
The area of the 8-in pizza is about in2, and costs $ per in2.
The area of the 10-in pizza is about in2, and costs $ per in2.
The better buy is the (drop list) pizza.
Options of drop list: 6 in., 10 in., 8 in.

see below

Step-by-step explanation:

Area of 6 in diameter pizza

r = 3

A = pi r^2

A = 3.14 *3^2 = 28.26 = 28.3 in^2

Cost = $/ area = 9 /28.3 =.31847 = .318

Area of 8 in diameter pizza

r = 4

A = pi r^2

A = 3.14 *4^2 = 50.24 = 50.2 in^2

Cost = $/ area = 12 /50.2 =.239

Area of 10 in diameter pizza

r = 5

A = pi r^2

A = 3.14 *5^2 = 78.5 in^2

Cost = $/ area = 18 /78.5 =.229299363=.229

The best buy is the 10 inch pizza

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
