Well, you never have a perimeter for a circle, you have to find the circumference. The perimeter is the length of the borders of a shape, and a circle has no border. The formula for circumference is, C= Pi multiplied by the diameter. To find the diameter just multiply the radius by two. Pi is a never ending number, but you should use it as 3.14 times the diameter

How do you calculate the circumference of a circle given the diameter or the radius?
Circumference = diameter*pi
What name is given to the perimeter of circle?
The perimeter of a circle is its circumference
How do you find the perimeter of a circle with radius 5cm?
Do note that the perimeter/circumference of a circle can be found using this formula: πD or 2πr. Hence, with the information given that the circle has a radius of 5cm, the circumference of the circle is: Formula = πD Diameter = Radius x 2 = 5cm x 2 = 10cm π = 3.14 (depending on what the question states π to be) Circumference of the circle = 3.14 x 10cm = 314cm
Given a circle with a radius of 6 what is the length of an arc measuring 60 degrees?
The length of an arc measuring 60 degrees given a circle with a radius of 6 is 2*pi, that is 6,2831 approximately.The perimeter of a circle is calculated with the formula:L = 2 * pi * rwhere L is the perimeter and r the radius of the circle. This is equivalent to calculating the length of an arc measuring 360 degrees. The length of any arc smaller than 360 is proportionally smaller. Given that 60 degrees is 1/6 of the total circle (360), the length of the arc will be 1/6 of the perimeter.2 * pi * 6L = --------------- = 2 * pi6
How do you find the perimeter when circumference is given?
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
