The diameter would be 8cm, because the diameter is always double the radius.
That's why the formula 2'Pi'r is also known as 'Pi'd.

If the radius of a circle is 4 cm what is the diameter?
Diameter: 2*4 = 8 cm
If the radius of a circle is 5 cm what is the diameter?
if a radius is 5cm the diameter is 10cm rule- you double the radius
If the radius of a circle is 4 cm what's the diameter?
8cm. The radius is always half the diameter.
What is circumference of a circle with a radius of 4 cm?
circumference formula is pi(diameter) diameter is 2(radius) radis=4; diameter=2(4)=8 pi(8)=circumference of the circle...this is the EXACT answer plug it into a calculator and you will get 25.1327412287 your welcome ;)
What is the diameter of a circle if the radius is 4 units?
8 units; the diameter of a circle is twice its radius.
