2 pi radius

how did u work out the radius? huh?!

well i would have done ur way phron... difference between the +26 and - 10 (+26 is the 26 sweets left and -10 is for the 10 sweetes short) then find the difference between 12 and 8 to find the difference of how much is given out. then divide it...

and algebra uses variables while reasoning uses words in stead of variables.. reasoning is much simpler than algebra.. for wat i say..

p.s the watermelon one really helped thanks i didn't know how to do that but i knew the answer

and i know the answer just testing if u know it... so i know u got it wrong...

here's another one;

A large watermelon weighs 20kg, with 98% of its weight being water. It is left in the sun and some water evaporates so that now only 95% of its weight is water. What does it now weigh?

p.s are u having trouble with the first on?

some hard questions are here!! no algebra!

give u guys a question now....
Uncle Ben is giving sweets to some kids. If each kid receives 8 sweets, 26 sweets remain. If each kid got 12 sweets, Uncle Ben will be 10 sweets short. How many kids are there?
