Answer:
16.84
Step-by-step explanation:
For perimeter, you are basically solving 2 different 1/2 circles
for the larger one, you do the equation: 3.14 x 4 = 12.56
For the smaller one, you do the equation: 3.14 x 2 = 6.28
12.56 + 6.28 = 18.84
and since I think you are putting em together you are supposed to remove 2 so the answer would be : 16.84
So, for the calculations (if doing area), you are gonna have to split the figures apart.
ok, for the first part, the 1/4 circles
Pi*2^2=12.566
12.566/4=3.1415
Since there is 2 of the same figure, you can do 1 of 2 ways
A. 3.1415x2 = 6.283
B. 12.566 / 2 = 6.283
Now for the 1/2 circle:
pi*1^2=3.142
3.142/2 = 1.571
Now to add:
1.571 + 6.283 = 7.854
