he is being ridiculous, and not accepting that he needs to know how to work out the area of a circle, using pi x radius squared.
can a teacher please tell me to that kids have covered how to work out the area of a circle using pi, coz he is being ridiculous, and saying it is a level stuff

Just asked DS2, Year 8, said def knows that but when questioned closely said learnt in Yr 8 but could have poss learnt it in year 7, but teacher 'was crap' so may not have understood it!!! Complete apologies to all teachers, his words not mine, but may explain OP's sons 'ridiculousness'. Hope this helps, rather than hinders.(btw is at grammar school).

I am a teacher and yes, everyone gets to learn the area of a circle and you always use pi x radius squared. there is no other way.

and when you do know how to do this it will seem so easy you will be shamefaced wondering what all the fuss was about.

honest.

Hi

pi x r2

pi is 22/7
so 22 divided by 7 times radius squared
first square radius the multiply by the answer you get by dividing 22by7.

does that make any sense?
