Answer:

Number 1 is 128.52 Number 2 is 18.56

Explanation:

Find the area of the partial circle

Diameter is 6 so the radius is 3

A=
$\pi r^(2)$

A=2*3.14*
3^(2)
3^(2) =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=
$\pi r^(2)$

A=3.14*
2^(2)

A=3.14*4

A=12.56 Add it to 6

A=18.56
