Question

It the curcumlerince of
cercallar Sheet

132 cm
find its radius
and area
432 cm​

Answer 1

Answer:

Answer:

The radius of the circle is 21 cm and the area of the circle is 1386  cm^{2}m2 .

Step-by-step explanation:

Given:

Circumference of the circular sheet = 132 cm

Formula used for finding circumference of a circle = 2\piπ r

Let us assume the radius of the circle as r.

Solving,

=> 2 * 22/7 * r =  132 ( Taking value of pie as 22/7)

=> 44/7r = 132

=> 44r = 132 * 7

=> 44r = 924

=> r = 924 / 44

=> r = 21

Therefore, Radius of the circle is 21 cm.

Now we have to find the area,

Formula for finding the area of = \piπ r^{2}r2

Area of the circular sheet = 22/7 * 21 * 21

= 1386 cm^{2}m2

Therefore, the radius of the circle is 21 cm and the area of the circle is 1386  cm^{2}m2
