2. The figure shows two semicircles. Find the area of the shaded region. Use 3.14 for pie.
6 cm
6 cm

4.71 (corrected to 3 significant figures)

Step-by-step explanation:

12 is the diameter of the big semicircle and 6 for the small semicircle

the radii of the big and small circles are 6 and 3 cm respectively

(6/2 × 3.14) - (3/2 x 3.14) = 4.712388.. = 4.71

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
