Answer 1

Answer:

52.26 cm

Step-by-step explanation:

Since the semicircle is a part of the rectangle, the side of the rectangle where the semicircle is put is eliminated. We know the diameter of the circle, if is 6 cm, but the formula of a semicircle is пr^2 / 2. To find the radius, we divide 6cm by 2, and then we square 3 (that's what we got), and get 9. We  simply multiply it by п, which would give us 28.26. The area of the rectangle is 4 * 6 = 24, and the area of the semicircle is 28.26. Now, we just need to add them: 24 + 28.26 = 52.26 cm, and that would be your answer.

Tell me if I'm wrong :)
