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.

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 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
Any inscribed in a semicircle is a?
All triangles inscribed in a semicircle with one side of the triangle being the diameter of the semicircle are right triangles.
How do you put semicircle in scentence?
The cross section of the Ram hemi is a semicircle
What is the formula of area semicricle?
The area of a semicircle is one-half the area of a circle. it is equal to (pi/2)r^2, where r is the radius.
