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 formula of perimeter of semi circle?

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 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 is the radius of a semi circle?

It is the same as the radius of the whole circle.
