it is greater than becuase lhalf x is half off of x so x is greater
2328.31286 cm2
The area would be 32*pi miles squared. The perimeter would be 16*pi miles.
i need the answer asap plz
It is 27.49 units.
it would be the diameter of the smaller circle times sqrt 2
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.
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.

The area of a semicircle with a diameter of 2x is given by the formula ( \frac{1}{2} \pi r^2 ), where the radius ( r ) is ( x ). Thus, the area is ( \frac{1}{2} \pi (x)^2 = \frac{1}{2} \pi x^2 ). The area of a circle with a radius of ( x ) is ( \pi x^2 ). Therefore, the area of the semicircle is less than the area of the circle, as ( \frac{1}{2} \pi x^2 < \pi x^2 ).
A semicircle is half a circle, so its area is half that of a circle: radius = 1/2 diameter = 22 ÷ 2 = 11 area = 1/2πr2 = 1/2π112 ~= 190 sq in
The diameter of the circle is 21.4 feet, approx.
Diameter of semicircle = 1 Area of semicircle = Pi/8 Area of triangle = 0.25 Area outside triangle = (Pi/8) - 0.25 = 0.1427 (rounded to 4th decimal).
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.
A semicircle is half of a circle, formed by cutting a circle along its diameter line. It has the same curved edge as a circle but only covers half the area. The formula for the area of a semicircle is 1/2 times π times the radius squared.
Twice as big.
It can have any value up to 392 square cm.
