Biggest size of circle that can be cut off will have the diameter
= the breadth of the paper = 21 cm

radius = 21/2 = 10.5cm

∴ Area of circle = πr² = (22/7)*(10.5)² = 346.5 sqcm

shubhangi19032002: the above ones are absolutely correct.

Lawliet: Would u Mind Being More Specific

Razz14: hey whats going on..??

Lawliet: Idk

shubhangi19032002: both of them are correct...that's what i mean.

Lawliet: Yup Ofcorse We Got The Same Answer After All

QwertyZoom: Idk, I didn't feel like it needed to be more specific, it looks specific enough already

Lawliet: No u got the wrong idea by being more specific i meant you to be specific about ur first comment as when u said the above ones so i was confused that by above u r refering to ur answer or mine

QwertyZoom: Ohh

The Biggest Circle What Can Be Cut By The Rectangular Piece Of Paper will have diameter = 21cm [as 21 cm is the wide of rectangle so more than that cant be cut]

So Radius Of Circle = Diameter/2
= 21/2 = 10.5cm

Now Area Of The Circle = pi r²
= 22 * 105 * 105
-------------------- [taking decimal out]
7 * 10 * 10
= 346.5 cm²

Area Of Paper Left = Area Of Rectangle - Area of Circle
= 30 * 21 - 346.5
= 630 - 346.5
= 283.5 cm²
Therfore,

Area Of The Circle= 346.5 cm²
Area Of Paper Left= 283.5 cm²
