Answer:

Explanation:

To find the area of a semicircle, you can follow these steps:

1. Recall that the formula for the area of a circle is A = πr^2, where A represents the area and r represents the radius.

2. Since a semicircle is half of a circle, the formula for the area of a semicircle is A = (πr^2)/2.

3. In this case, the radius of the semicircle is given as 3cm. Plug this value into the formula: A = (π * 3^2)/2.

4. Simplify the equation: A = (π * 9)/2.

5. The final answer, in terms of π, is A = 4.5π square centimeters.

Therefore, the area of the semicircle with a radius of 3cm is 4.5π square centimeters
