For all of these answers, the equation used was (AB + CD)/2 = EF

1.12+24=36    36/2=18
2. 21 + 35 = 56    56/2 = 28
3. (7 + EF)/2 = 9 
    multiply by 2
   7 + EF = 18
   subtract 7
EF = 11

4. (AB + 32)/2 = 22
Multiply by 2
AB + 32 = 44
Subract 32
AB = 12

5. Average

Please help me!!!!!!!!!!!!!!!
Ainat [17]

r = 7.53 so d = 2r = 2(7.53) = 15.06 cm

Area of square = d^2 / 2 = (15.06)^2 / 2 = 113.41 cm^2

Area of circle = 3.14 (7.53)^2 = 178.04 cm^2

Area of yellow region = Area of circle - Area of square

Area of yellow region = 178.04 cm^2 - 113.41 cm^2

Area of yellow region =64.63 cm^2 = 64.6 cm^2 (nearest tenth)

Answer

64.6 cm^2
