What does distance mean?

I got re taught about it in "Key skills adult numeracy" at college 2 months ago and as soon as i walked out that class, gone, but i got my level 2 pass on the test (just about) so thats all that matters

I do believe that one of your formulae is wrong...

The circumference is 2(Pi)r, the area of the circle is (Pi)r2 (that's squared).

Thats what I meant, you only spotted one of Keiths

no, 2 out of 3 there.

circumference formulae
you gave the formulae for the area of a circle. Back to school for you

edit, whoops Ed got in before me

not knowing that beef comes from a cow is rather shocking

I knew someone who was really confused at why sheep didnt shrink when it rains (yes really!).

We had a girl start working in our office with 4 A's at A-Level, we thought she'd be really bright, but she didn't understand the concept of length, width, height for measuring a rectangular box and she thought Dublin was in the UK!

Sometimes I wonder whether all you have to do nowadays is spell your name correctly on the exam paper to get an A!

Incidentally, back in 1975 when I sat my apprenticeship exam for Leyland Trucks, one of the questions was to calculate the circumference of a circle. It was therefore assumed back then that the average 16 year old would know how to do this.

I realised that as I pressed post but I was called away from the computer so couldn't change it.

Where's me dunce hat?
