The radius of a circle is half the diameter. So if the diameter is 5cm, the radius would be 2.5cm.
Radius is from the centre to edge so is 5cm.

Pi x radius(R) squared e.g radius of circle is 5cm A=3.14x5 squared Area is 78.5
Diameter = 14cm so radius = 7cm. Height = 5cm. Take pi as 22/7 Volume of a cylinder = pi*radius2*height Volume = 22/7*72*5 = 770 cubic cm.
The circumference of a circle, if its diameter is 5cm, is about 15.71cm
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

The diameter is twice the radius.
Radius is from the centre to edge so is 5cm.

The circumference of a circle with diameter D is πD where π = 3.14159 approx. So D = 5 gives a circumference of 15.7 cm
