Area of a semicircle is 1/2* πr^2
Area of a square is s^2
Square’s area: 4mm^2
The radius is 3mm
Plug into the equation
1/2* π(3^2)
1/2* π(9)
We can use 3.14 as an estimate of pi
1/2*28.26
14.13mm^2
Now just add them both
Total area 18.13mm^2
O, C , B , A because the important will disguise the sisomatic amplitude
Answer:

Step-by-step explanation:
It must end in
(divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).
The digit sum is
.
We want to make
as low as possible because it's a higher digit than
.
If
is as low as possible, we have that the sum is
. Uh-oh.
has to be even! So
doesn't work.
If
, we have that the sum is
. Yay!
So, the answer is 
Answer:
your answer to that is D hope that helps
