area of small circle = PI x r^2
r = 1/2 the diameter ( 1/2 * 3 = 1.5)

3.14 x 1.5^2 = 7.065 square cm

there are 2 small circles so total area for them = 7.065 * 2 = 14.13 square cm

the area for the large circle = PI x r^2
the radius of the large circle is 3 cm

3.14 x 3^2 = 28.26 square cm

the area of the shaded area is: 28.26 - 14.13 = 14.13 square cm, which can round down to 14 square cm.
