Answer:
164.48 or 164.5
Step-by-step explanation:
So, to make it simpler, you can do the circle like this: 3.14×(8×8). Then you can work down!
3.14 × 64
200.96
and then because it's halved, you divide by 2
100.48
then that's the half circle
The square would just be 8×8=64
then add the circle and the square and viola!
164.48
