Area of a semicircle = (pi*radius^2)/2
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} ).
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.
You use the equation Area = width x length. And solve for the width. You solve it by dividing both sides by the length to get.. Area/length = width

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.
The equation of a semicircle with center at (h, k) and radius r is given by: (x - h)^2 + (y - k)^2 = r^2, where x and y are the coordinates of a point on the semicircle.
x2+y2=r2, y>=0
It is 27.49 units.
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.
I think that you are asking for the equation of a semi-circle. If you have a circle with radius r and centered at (0,0), its equation is x^2 + y^2 = r^2 The upper semicircle has the equation: y = sqrt(r^2 - x^2) with -r ≤ x ≤ r <------------------ Answer By using the square root I only get points where the y coordinate is positive and thus all points are restricted to the upper semicircle. The area is ((π * r^2) / 2) The perimeter is (π * r)
Pi*radius squared is how to find the area of a semicircle
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).

Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
you don't answer an equation, you solve an equation
