Question

Find the perimeter of this figure it is made up of semicircles and quarter circles

Answer 1

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
