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)

How do you find the radius of a semicircle?
it is have the diameter
How do you calculate the radius of s semicircle?
Calculating the radius of a semicircle depends on what information about the semicircle is given.
How do you find the distance around a semicircle?
It is half the circle's circumference plus its diameter.
How would you find g field which produces semicircle using equation of semicircle and y?
semicircle PQR of diameter 10 cm.semicircle PAB and BCR of diameter d1 and d2 respectively are inscribed in the semicircle PQR or such that the sum of d1 and d2 is equal to 10 cm. determine the relation between the lengths of arcs PQR,PAB, and BCR.
What is the formula to find the area of a semicircle?
Pi*radius squared is how to find the area of a semicircle
How do find the circumference of a recttangle and semicircle put together?
If the semicircle is placed on 1 side of the rectangle:Find the total perimeter(circumference) of the side opposite to the one with the semicircle's base and the 2 sides perpendicular to the semicircle's base.The formula for circumference of a circle is 2πr.Thus for the semicircle we will take the circumference as πr.Find the sum of 1st and 2nd points. This is the final answer.
What is the formula of a semicircle in perimeter?
The perimeter of a semicircle with radius R is pi*R + 2*R = R*(pi + 2)
How do you find the diameter of a semicircle when radius is given?
The diameter of the semicircle will be twice the radius.
What is the formula for a semi-circle?
There is no formula for a semicircle. There is a formula for the perimeter of a semicircle, a different formula for the area of a semicircle, and another one to generate a semicircle in the Cartesian plane. You must specify which of these you want a formula for. Also, there may be additional information that is required to put the formula in the context of the available information. For example, the formula for the area will differ depending on whether you know the length of the straight side or the semi-circular arc.
What is the formula for finding the distance around A semicircle?
It is: (pi*radius)+(diameter)
How do you find the radius of a semicircle?
it is have the diameter
How do you find the perimeter of a shape that has a semicircle?
To find the perimeter of the curved section of the semi-circle: Perimeter of semicircle = Pi x radius If you also need to the find the perimeter of the straight part of the semicircle (the diameter), it is simply double the radius.
What formula is apply to find area of semi circle?
If the radius of the circle is R, then the area of the whole circle is πR2 So the area of the semicircle is 0.5*πR2
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.
How do we find a perimeter of a semicircle?
It is its diameter plus half of its circumference
What is the formula for the perimeter of a semicircle?
If you are given the diameter 'D' of the circle: the full circumference is (pi times D) the perimeter of the semicircle is half this plus the diameter Therefore: Pi x D /2 + D
