Well, darling, a semicircle is half of a circle, so to find the area you just take the area of a full circle and divide it by 2. The formula for the area of a circle is πr^2, so for a 10cm semicircle, you'd calculate it as 0.5 * π * 5^2, which gives you an area of 39.27 square centimeters. Voilà!

How do you find the area of a semi-circle radius 10cm?
πr² is the formula for finding the area of a circle. To find the area of a semicircle just divide the answer by two. So take the radius, square it, which in this case would be 100, multiply it by π [pi (3.14)] and divide it by two.
What area is 10cm x 10cm. 10cm2 or 100 sqcm?
A square that measures 10cm on each side has an area of 100 square centimeters. This is calculated by multiplying the length of one side by itself (10cm x 10cm = 100 sqcm). The unit for area is always squared, so the area of a 10cm x 10cm square is 100 sqcm.
Find the perimeter of a semicircle of diameter 10cm?
First find the circumference of the whole circle using Pi x diameter. Halve the answer and add the diameter. Thus: 3.1416 × 10 = 31.416 ÷ 2 + 10 = 25.708cm So the perimeter of the semi-circle is 25.7cm
