If the radius of a circle is 1 cm what is the circumference of the circle?

we know circumference=2*pi*r; where r=1; circumeference=2*3.14*1=6.28 cm

What is the circumference of a circle with radius 12cm in fraction?

The circumference of a circle is C = 2Ï€r, where C is circumference, Ï€ is pi (3.14), and r is radius. C = 2 x 3.14 x 12cm = 75cm = 75/1 cm

How is pi in relation to a circle?

Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).

If the circumference of a circle doubles the radius?

IMPOSSIBLE circumference = 2*pi*radius if circumference = 2*radius: 2*radius=2*pi*radius 2*radius/(2*radius)=2*pi*radius/(2*radius) 1=pi pi= 1 therefore it is impossible to have a circumference that is twice that of the radius

How do you find the radius of a circle if the central angle is 36 degrees and the arc length of the sector is 2 pi cm?

The measure of the central angle divided by 360 degrees equals the arc length divided by circumference. So 36 degrees divided by 360 degrees equals 2pi cm/ 2pi*radius. 1/10=1/radius. Radius=10 cm.
