Radius = 1/2 of diameter = 4 cm
2 cm
Radius = Diameter / 2 In this case, diameter = 8 cm so radius = 4 cm
It is: 2*4 = 8 cm
Radius of a circle with diameter 4? Radius is half of the diameter, so in this case it would be 2.
Radius = 1/2 of diameter = 4 cm
Diameter: 2*4 = 8 cm
diameter =2*radius =2*2 cm = 4 cm
2 cm
Radius = Diameter / 2 In this case, diameter = 8 cm so radius = 4 cm
if a radius is 5cm the diameter is 10cm rule- you double the radius
8cm. The radius is always half the diameter.
It is: 2*4 = 8 cm
10 cm
Radius of a circle with diameter 4? Radius is half of the diameter, so in this case it would be 2.
Well, darling, the area of a circle with a radius of 2 cm is approximately 12.57 square cm (π x radius squared). As for the circumference, it's around 12.57 cm (2 x π x radius). So, there you have it - a little geometry lesson to spice up your day!
let d = diameter let r = radius r = d ÷ 2 r = 8 cm ÷ 2 = 4 cm
