This is the second test of the topic covered in CBSE course 'Areas related to Circles'.

This part contains areas of Circles, Concentric Circles, Major and Minor Sector, Major and Minor Segment, Areas of combined figures and so on. Also the circumference of circle and the given figures are to be found out.

This is an MCQ test based on the pattern of CBSE board. Whomsoever are appearing for the 2012 board exams, it will be helpful to them. As section I of board papers consist of Mutiple Choice Question. All the best.

Nidhi ShrivastavaLet R and r be the radius.

Circumference ( R ) = 2 *pi* R

Circumference ® = 2*pi* r

Diffrence= 132= 2*pi * (R-r)

If x is the width then

132 = 2* 3.14* ( r+x-r). ( R = r+ x)

132= 6.28 x

X= 132/6.28=21.019m

The width is 21.019m or 21.02 m
