Maths problem - help!

errr. 40mm?

That's what came to mind but doubt very much it will be right.

sorry! meant 140mm not 40.

Yes about 140 or 137 to be exact

do they overlap?

My picture in my mind of a mandala would have a circle touching the outer circle at every three degrees but what do I know!

Roderick take your finger off that button immediately!

If they overlapped, Jess, that would be a whole new ballgame!

No - they do not overlap; and there needs to be a small space between each. I have come to the conclusion that circles of about 20cm would fit the bill.

As they say in a GCSE exam, could you please show your working Roderick.

(But not necessarily x 8!)

120 circles with a radius of 137mm. would have a total area equal to that of the proposed circle containing them, but thus makes no allowance for the spaces between the small circles, so they would have to be significantly smaller.

Hmm.

As evry fule nose, the answer is ...........42.

Of course, phoenix! But 42 what? Are zaphods a useful unit of measurement in this context?

Just had sight of the KS2 Maths paper for 10/11 year olds

n stands for a whole number

2n is greater than 30
5n is less than 100

Write all numbers that n stands for

I wonder how many adults could tackle that one with ease?

My GD has been doing her KS2 maths today. I think she thought the mental maths paper was hard, but the second paper was OK.

My GD is also doing SATs this week. I think today is the last of them.

I found that question easy.
