Answer:
Number 1 is 128.52 Number 2 is 18.56
Step-by-step explanation:
Find the area of the partial circle
Diameter is 6 so the radius is 3
A=[tex]\pi r^{2}[/tex]
A=2*3.14*[tex]3^{2}[/tex] [tex]3^{2}[/tex]=9
A= *3.14*9
A=28.26
Now find the area of the rectangle
A=lw
A=6*12
A= 72
Add both of the answers
Answer is 128.52
Number 1
For triangle
A=1/2bh
A=1/2*3*4
A=1/2*12
A=6
Find the area of the circle
Diameter is twice a radius so the radius would be 2
A=[tex]\pi r^{2}[/tex]
A=3.14*[tex]2^{2}[/tex]
A=3.14*4
A=12.56 Add it to 6
A=18.56
