The area of a semicircle can be calculated using the formula ( A = \frac{1}{2} \pi r^2 ), where ( r ) is the radius. Since the diameter is given as ( Cm ), the radius ( r ) is ( \frac{Cm}{2} ). Plugging this into the formula gives ( A = \frac{1}{2} \pi \left(\frac{Cm}{2}\right)^2 = \frac{\pi (Cm)^2}{8} ). Thus, the area of the semicircle is ( \frac{\pi (Cm)^2}{8} ).

How do you find the area of a semi-circle if you know the diameter?

A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.


What is the diameter of a semicircle?

In a semicircle, the diameter is the straight line. It is also equal to double the radius, and that property allows it to be used when calculating area and circumference.

What is the perimeter of a semicircle if the diameter is 8cm?

Well, darling, the perimeter of a semicircle is the sum of the semicircle's curved edge (half the circumference of a full circle) and the diameter. So, with a diameter of 8cm, the curved edge would be half of the circumference of a circle with a diameter of 8cm, which is 8π cm. Add that to the diameter, and you get a sassy perimeter of 8π + 8 cm, or approximately 33.13 cm.

What is the perimeter of a semicircle with radius 8cm?

A semicircle is half a circle. So the perimeter of a semicircle is half the circumference of the whole circle plus the diameter, which is twice the radius: perimeter = 1/2 x 2{pi}r + 2r perimeter ~= 3.14x8 + 2x8 ~= 41.13cm
