<< < (6/22) > >>

Q80BOY:
come on guys,

i need help, the exam is after 1 week !!

Guthixol:
:P circumference of a circle =2?r, so the answer of b(i)=75cm in diameter. but they want the radius to calculate the answer. half of 75 which is 37.5.    C=2?(37.5)=236cm



I hope i am right :P

Guthixol:
ok the ? means pie, i tried typing the symbol but it dosent work :P so ?=pie

Guthixol:
