Question

if the circumference of a circular sheet is 132 cm find its radius​

Answer 1

Hi✌️✌️

SOLUTION:-

Given:

The circumference of a circular sheet is 132cm.

To find:

•Radius

•Area of circular sheet.

Explanation:

The distance around a circle is called the circumference.

We have,

Circular sheet= 132cm

We know that, formula of the circumference of the circle= 2πr

=) 2 × 22/7 × r = 132

=) 44/7 ×r = 132

=) r= 132 ×7 /44

=) r= 3×7

=) r = 21cm

Now,

Area of the circular sheet = πr²

=) 22/7 × 21cm × 21cm

=) 22 × 3cm×21cm

=) 1386cm²

Thus,

The radius of the circular sheet is 21cm.

The area of the circular sheet is 1386cm².
