Question

The length and breadth of a rectangular paper are 35 cm and 22 cm . Find the area of the largest circle that can be cut out of the paper. (Take value of pi as 3.14)

Answer 1

We are given:
Length of paper = 35 cm
Breadth of paper = 22 cm


(All figures are in cm.)

The area of the largest circle that can be cut from the rectangular paper has a diameter equal to the breadth of the paper.

Therfore, diamter, d = cm
We also know that radius r = d / 2 = (22 / 2) cm = 11 cm

Now, calculating area of a circle of radius 11 cm :-
$Area={\mathrm{\pi r}}^2=3.14\times {11}^2=379.94m^2$
This is the required answer.
