Question
The length and breadth of a rectangular paper are 35 cm and 22 cm. Find the area of the largest circle which can be cut out of this paper.
Solution
Length = 35 cm
Breath = 22 cm
The largest circle which can be cut from the rectangle will have,
radius = `22/2` cm = `"D"/2` = R = 11 cm
Area of circle = `pir^2`
= `22/7 xx 11 xx 11`
= 380.28 cm2
