- Area = (πr 2 )/2
- Area = (π x 5 cm x 5 cm)/2
- Area = (π x 25 cm 2 )/2
- Area = (3.14 x 25 cm 2 )/2
- Area = 39.25 cm 2

Advice
- The area of the semicircle is (1/2)(pi)(r^2).
- The area of the circle is (pi)(r^2)
Warning
- Note do not use the attached line to calculate the area! If given a diameter, then you must remember to divide by 2 to get the length of the radius.

In conclusion, calculating the area of a semicircle is a straightforward process that requires understanding the formula and steps involved. By utilizing the formula A = (π * r^2) / 2, where A represents the area and r represents the radius, one can easily determine the area of a semicircle. It is essential to remember that a semicircle is half of a full circle, and therefore, the area calculation must account for this by dividing the result by 2. Additionally, it is crucial to use the correct units of measurement for both the radius and area to maintain accuracy. Overall, with a clear understanding of the formula and careful attention to detail, calculating the area of a semicircle can be accomplished efficiently.
