Half the Circumference + the DiameterCircumference of a circle = pi X d ,so perimeter of a semi-circle = (3.142 X Diameter) + Diameter

The boundary or perimeter of a circle is called the circumference. The formula for calculating the length of the circumference is C = 2πr.

In a circle of radius, r, perimeter of quadrant = pi*r/2 + 2r = r*(pi/2 + 2)

To find the circumference (distance around) of a circle, use the formula pi x d (d=diameter)

this is called finding the circumference. The formula is 2*pie*radius

to find the perimeter of a circle you simply do this (pi x D )

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)

There is no specific formula for a sector of a circle. There is a formula for its angle (at the centre), its perimeter, its area.

The formula for the circumference of a circle is pi * diameter or (2 radius.)

The perimeter is equal to Pi times the diameter.

The answer will depend on what the formula is for: the perimeter or area of the segment.

There are different formula for: Height, Area, Perimeter, Angle, Length of Median Radius of inscribed circle Perimeter of inscribed circle Area of inscribed circle etc.

The formula for the perimeter of a whole circle is 2 π r therefore the perimeter of a half circle will be (2 π r)/2 which is π r n.b. the perimeter of a circle is normally referred to as the circumference...

2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi

There is no such thing as the perimeter of a circle. The circumference, however, is 12.4*pi (since the formula is pi*diameter)

2*pi*radius or pi*diameter
