Math

In math we have been learning about radius, circumference and diameter. The circumference is the distance around the circle. The diameter is the distance vertical or across the circle. The radius is half of the diameter. When you do questions involving these, you have to use pie witch is 3.14 and also you have to always show your work.

Here is some examples:
C = pie x D
C = 3.14 x 2cm
C = 6.28cm

C = pie x D
C = 3.14 x 60mm
C = 188.4 mm
