Simple Circumference of a circle

Circumference is

• another term for the area of a circle

• another term for the perimeter of a circle

• another name we give a circle

• another term for the perimeter of any shape

Diameter is

• the name given to the straight-line distance across a circle through it's centre

• is half of the radius

• the name given to the perimeter of a circle

• the name given to the area of a circle

A circle's radius is always half the length of it's diameter

• True

• False

For the following circle

• The Diameter is 8cm and the Radius is 16cm

• The circumference is 16cm

• The Diameter is 16cm and the Radius is 8cm

• The Diameter is 32cm and the radius is 16cm

For the following circle

• The circumference is shown

• The Diameter is shown

• The Radius is shown

For the following circle

• The Radius would be 12cm

• The Diameter would be 12cm

• The circumference would be 12cm

 $C\ =\ \pi\times Diameter$  is the formula to work out Circumference of a circle

• True

• False
