The perimeter of a circle has the formula 2πr. Therefore the length of a semi circle is πr. But the perimeter of a semi circle also includes the diameter which is 2r.
Therefore the perimeter of a semi circle = πr + 2r = r(π + 2)

How do you calculate the perimeter of a semi circle?
The perimater of a circle is the same as the circumference of a circle, but if it's only a half of a circle (semi-circle) you would use the formula 2*pi*r/2 If it's a quarter of a whole circle, or a fifth of a circle, then you would divide it by 4 or 5.
How do you find the perimeter for a semi circle?
Its perimeter is half of its circumference plus its diameter
What is the formula of a perimeter of a circle?
to find the perimeter of a circle you simply do this (pi x D )
What is the perimeter of a semi circle?
The perimeter of a full circle is 2*pi*r. Where, pi is the mathematical constant that is the ratio of any circle's circumference to its diameter, approximately equal to 3.14, and r is the radius of the circle. The perimeter of a semi circle, assumed to be half of a full circle is pi*r where pi and r are previously defined.
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 perimeter of a semicircle?
Half the Circumference + the DiameterCircumference of a circle = pi X d ,so perimeter of a semi-circle = (3.142 X Diameter) + Diameter
Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
How do you find the perimeter of a semi circle with a diameter of 12mm?
-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).

How do you find the perimeter of a rectangle with a semi circle attached to it?
add the perimeter of the rectangle, minus the side that'c covered by the semi circle. then, find the circumference of the semi circle [diameter x pi, divided by 2] and addd them together
