Question

A sheet is 11 cm long and 2 cm wide. circular pieces 0.5cm diameter are cut from it to prepare discs. calculate the number of discs that can be prepared

Answer 1

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.
