Answer:

C = 60pi cm or approximately 188.4 cm

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

C = 2* pi * 30

C = 60 pi

We can approximate pi by 3.14

C is approximately 60*3.14 or 188.4

The figure is made up of two shapes a semicircle and a square.

fiasKO [112]

Answer:

Option B $(2 \pi+12)\ cm$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The perimeter of the figure is equal to sum the length of semicircle plus the length of three sides of a square

<u>Find the length of semicircle</u>

Remember that the circumference of semicircle is equal to

$C=\frac{1}{2}\pi D$

we have

$D=4\ cm$

substitute

$C=\frac{1}{2}\pi(4)=2 \pi\ cm$

The perimeter of the figure is equal to

$P=2 \pi+3(4)=(2 \pi+12)\ cm$
