About circles, select the right options only.
The radius is the double of the diameter
If the diameter is 13 cm, the radius is 6.5 cm.
Circumference means the distance around a circle.
Diameter divided by Circumference = "Number pi "

40.9 cm
42.6 cm
41,9 cm
41.6 cm
Loot at the picture. Select the correct answers only.
CD = CB
CD is a diameter
BC = 2 x AC
AC = AB = AD
To estimate a calculation using
number π , this needs to be:
π = 3
π = 3.1
π = 3.14
π = 3.2
Using C = 2 π r , calculate the circumference of the circle shown on the picture.
C = 18.574 cm
C = 17.584 cm
C = 15.784 cm
C = 17.548 cm
