marty ' s pizza shop guarantees that their pizzas all have at least 75 % of the surface area covered with toppings, with a crust of uniform width surrounding them. if you order their best seller – a circular pizza with a diameter of 16 inches – what is the maximum width you can expect to see for the crust?

divide(subtract(16, multiply(sqrt(divide(divide(multiply(circle_area(divide(16, const_2)), 75), const_100), const_pi)), const_2)), const_2)
total area = 8 * 8 * pi radius = 64 pi surface = . 75 * 64 * pi = 48 pi radius of surface = 4 sqrt ( 3 ) ~ 6.8 radius width = 8 - 6.8 = 1.2 answer : b
