Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.

the circumfrence of a circle is pi times it's radius squared.

34cm

4 x 5cm = 20cm

circumference = 2pi * r = 2(3.1416) * 5 cm = 31.4159 cm i hope that helps

The circumference of a circle with a radius 5cm is: 31.4 cm

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

The radius of a circle is half the diameter. So if the diameter is 5cm, the radius would be 2.5cm.

Radius of a circle is half its diameter, 1/2 of 5cm =2.5cm

Exactly the same because the perimeter of a circle is its circumference

The radius is 0.795cm

5cm

The circumference of a circle 5cm in radius is about 31.42cm

The radius is approx 0.7958 cm.

2.5cm !

10cm

The diameter is twice the radius.
