Question

A circle of diameter 14cm is cut out from a sheet of square paper of sides 14cm. What is the area of the remaining paper?

Answer 1

Answer:

given,d=14 ,

r=14/2=7

and side of sheet =14cm

area of circle =πr^2

=22/7(7^2)

=22/7(49)

=22(7)

=154cm^2

area of square=a^a

=14^2=196cm^2

area of remaining sheet =area of square-(area of circle)

=196-154=42cm^2
