Solution;-
Total number of discs can be prepared = Area of the sheet/Area of one circular disc
Area of the sheet = L*B
Area of one circular disc = πr²
Area of the sheet = 11*2 = 22 sq cm
Area of one circular disc = 22/7*0.25*0.25
⇒ (22)/(22/7*0.0625)
⇒ 112 discs
So, total 112 discs can be prepared.
