The equation for area of a circle is A=pi x R x R. A semicircle is half a circle, so we calculate the area of a circle and divide by 2. The area of the circle would be approximately 1384.74. Thus the area of the semicircle would be 692.37.

What is area of semicircle?

The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.

How do you find the area of a semicircle using pi?

To find the area of a semicircle, you first need the radius (r) of the semicircle. The formula for the area of a full circle is ( A = \pi r^2 ). Since a semicircle is half of a circle, you divide that area by 2: ( \text{Area of semicircle} = \frac{1}{2} \pi r^2 ). Thus, the area of the semicircle can be expressed as ( \frac{\pi r^2}{2} ).

What is the area of the semicircle of 22mm?

The area of a semicircle can be calculated using the formula ( A = \frac{1}{2} \pi r^2 ), where ( r ) is the radius. For a semicircle with a diameter of 22 mm, the radius is 11 mm. Plugging this into the formula gives ( A = \frac{1}{2} \pi (11)^2 \approx 190.99 , \text{mm}^2 ). Thus, the area of the semicircle is approximately 190.99 mm².


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.
