Question : 13 of 50

Marks: +1, -0

Column A	Column B
Area of the shaded portion	304 $\cm^2$

Solution:

Solutions (13−16):
Area of shaded region

=60/360×πr^2

=60/360×22/7×14×14

=102.66\cm^2

Area of inner circle

=πr^2=22/7×7×7

=154\cm^2

Circumference of outer circle

=2πr

=2×22/7×7=44\cm

Area of ring

= π(R^2-r^2)

=22/7(196-49)=462\cm^2

163.

Column A	Column B
102.66 $\cm^2$	304 $\cm^2$

So, Column B is greater than Column A.
