Question

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

KnowledgeBoat · Accepted Answer

Given, Diameter of circle = 0.5 cm. From figure, Area of sheet required to cut a circle = area of a square with length of side equal to diameter. ∴ No. of discs prepared = No. of squares formed from sheet. No. of squares that will be formed from sheet = Hence, no. of discs that can be prepared = 88.
