Question

The radius of a circular disc is 14 cm
Find its area and perimeter.

Answer 1

Area of circular disc=πrsquare
22/7×14×14
22×2×14
44×14
616 sq.cm

Answer 2

radius=14cm (given)
area of circle=
$\pi \: r ^{2}$

=22/7 ×14×14
=616cm2
perimeter of the circle is also referred as circumference
$c = 2\pi \: r$
=2×22/7 ×14
=88cm
