perimeter = pi * diameter, or 2 * pi * radius
perimeter = circumference
The circumference of a circle is the length of the circle's perimeter.
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
The area of a circle is described by the equations: A=πr2 and the perimeter of a circle is described by the equation: C=πd where: A is the Area C is the circumference, or perimeter r is the radius d=diameter=2r π= pi, the ratio of diameter to circumference (3.14159)
to find the perimeter of a circle you simply do this (pi x D )
The perimeter of a circle is calculated using the equation Pi x D = 3.14 x 5 = 15.7cm
If 'R' is the radius of the circle, then-- area of the circle is [ pi R2]-- perimeter of the circle is [ 2 pi R ]
-- 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).
Its perimeter is half of its circumference plus its diameter
The perimeter or circumference of a circle = diameter times pi
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...
