Rachel is frosting the top of two cakes and wants to know which cake will require more frosting. one cake is round with a diameter of 8 inches. the other cake a square with the length of 9 inches. the top of which cake has a larger area? how much larger is it?

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

i think the correct option is the second option.

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
