Answer 1

Answer:

37.7

Step-by-step explanation:

perimeter of semicircle = 1/2 π d

                                       = 1/2 π (6)

                                       = 9.425 x 4 semicircles

                                       = 37.7

Answer 2

Answer:

P=37,68

Step-by-step explanation:

Those are 4 semi-circles, so basically 2 circles

The diameter of the circles d=6

$p =2 \times d \times \pi$

$p = 2 \times 6 \times 3.14$

P=37,68
