Question

From a circular sheet of radius 14cm ,two circles of radius 3.5cm and two squares of side 3cm are removed from the circle .find the area of remaining sheet

Answer 1

Step-by-step explanation:

We have given radius of bigger circular sheet = 14cm,  

smaller circular sheet = 3.5 cm  

and length and breadth of rectangle is 3cm and 1 cm respectively.

Area of rectangle = length ×breadth

= 3 × 1  

= 3cm2  

Area of remaining sheet  

= Area of bigger circle – Area of both smaller circle – Area of rectangle

= 616 – 77 – 3  

= 616 – 80 = 536 cm2  

Hence area of remainimg sheet is 536 cm2
