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

Answer 1

Explanation:

1) Circumference of cake = 25 1/7 inches

`2\pi r = (176)/(7)\\\\ 2*(22)/(7)*r=(176)/(7)\\\\r=(176*7)/(7*2*22)\\\\`

r = 4 inches

Area of cake = πr²

`=(22)/(7)*4*4\\\\`

= 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
