The square cake is has a larger area by about 40.73 square inches

Step-by-step explanation:

Find the area of the top of each cake.

The square cake has an area of 81 sq inches, (length x width = Area, the

length is 9)

The round cake has an area of 16π, which is about 50.27 square inches

(A = πr², here r is 4, radius is half the diameter)

81 - 16π = 81 - 50.27 = 40.73 square inches
