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 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.
What is the equation to solve the area of a semicircle?
Area of a semicircle = (pi*radius^2)/2
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 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 to find the area of a semicircle?
Pi*radius squared is how to find the area of 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.
What is the area of the semicircle (use 3.14 for and rho)?
That would depend on the radius which has not been given but the area of the semi circle will be (pi*radius squared)/2
What is the equation to solve the area of a semicircle?
Area of a semicircle = (pi*radius^2)/2
Half of a circle?
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.
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 use the word semicircle in a sentence?
John drew a semicircle on his page with his compass in math class. Drew turned in a semicircle and struck hard with the stick in the general direction of the pinata.
What is the area of the semicircle if the length of the arc of a semicircle is 10 and pi feet?
It is 27.49 units.
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)
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.
What is the area of a semicircle when the radius is 21?
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.
