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
π = 3.14 (depending on what the question states π to be)
Circumference of the circle = 3.14 x 10cm
The circumference of a circle with a radius of 5cm is: 31.42 cm
The circumference of a circle with a radius 5cm is: 31.4 cm
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
The circumference of a circle 5cm in radius is about 31.42cm
Pi x radius(R) squared e.g radius of circle is 5cm A=3.14x5 squared Area is 78.5
The radius is approx 0.7958 cm.
