at a certain pizza parlor , the diameter of a large pizza is 40 % larger than the diameter of a small pizza . what is the percent increase in total amount of pizza , from a small to a large ?
a real world problem — - yum ! — - but again , the specifics of the shape don ’ t matter . diameter increases 40 % , so k = 1.4 in this case . “ amount of pizza ” just means the area of the circle , so k ^ 2 = ( 1.4 ) ^ 2 = 1.96 , which is the multiplier for a 96 % increase . that ’ s the percent increase in area . answer = e
divide(subtract(power(add(const_100, 40), const_2), power(const_100, const_2)), const_100)
