A basic baker starts making super-realistic cakes. Her most recent creation is a jack-o-lantern for Halloween.

Question

When completed, it weighs 2000 g and is 12 inches tall, and she charges $55. A customer requests the same cake but asks that all the dimensions be made 10% larger.

How tall will the new jack-o-lantern be?: 13.2 inches. How much will the new jack-o-lantern weigh?

Answer 1

v=hpir^2

new v = 1.1hpi(1.1r)^2=pir^2(1.1)^3= 1.1^3(old v)

new weight = 2000(1.1)^3

= 2,662 grams
