Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
If 'R' is the radius of the circle, then-- area of the circle is [ pi R2]-- perimeter of the circle is [ 2 pi R ]
to find the perimeter of a circle you simply do this (pi x D )
The perimeter or circumference of a circle = diameter times pi
The answer depends on what information you have about the circle. If you know the radius, thenArea = pi*r^2 and perimeter = 2*pi*r
Multiply the diameter by pi.
Of a circle,the area is: Pi * r^2,perimeter is: 2* Pi * rWhere, r is the distance from the circle's center to the perimeter, and Pi is a constant: Pi ~ 3.14.
The perimeter or circumference of a circle = 2*pi*radius or pi*diameter
The perimeter which is the circumference of a circle is: pi*diameter or 2*pi*radius
Perimeter = pi*diameter = 113.1 cm
multiply 2.5 by pi pi x 2.5
The equivalent of a "perimeter" in a circle is actually called its circumference. To get the diameter, just divide the circumference by pi.
