Area of a Circle: u07_l2_t3_we3 Area of a Circle

We watched the video about how to work out the area of a circle because the formula A=πr^2 that means radius squared that is half of the dimeter so if we have a chocolate that has the diametre is 18mm so 18mm halved is 9mm then 9mm squared is 81mm then 81mm multiplied by π

π=Pi
r=Radius
