It's A
because it can be into a decimal and then to an equation
432-240=192
192 is the amount of shoes produced in 4 hours
194/4=48
48 is the amount of shoes products per hour
I think the answer is 2,612.48 because if you multiply the radius, 80 by itself you get 640. Then if you multiply 640 by 3.14 and then multiply the product by 1.3 you get 2,612.48.
