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
