Hey, just a quick question
do you know how to find the circumference of a circle by using the diameter
do if the diameter is 12.3cm what would it be and how would you work it out ?
thanks
right so just let me check to see if this is right, if it is im sorted
the question was find the area of a circle using diameter=14.8cm
so i do 14.8 divided by 2=7.4 then pie x 7.4squared=172.3
is this right?
