Pls Help me people keep getting it wrongpls the is half of my grade in the class please help Please name them too

Step-by-step explanation:

1) Circumference of cake = 25 1/7 inches

r = 4 inches

Area of cake = πr²

                     = 50.2857

                     =  50.29 in²

2) Area of square = side *side = 5 * 5 = 25 ft²

Diameter of semicircle = 5 ft

radius = 5/2 = 2.5 ft

Area of two semi circles = 2 * (1/2) πr² =  πr²

                                         = 3.14 * 2.5 *2.5

                                        = 19.625

                                         = 19.63 ft²

Area of the part of logo that still is green = 25 - 19.63

                                                                       = 5.37 ft²
