Question

A square of side 7cm is inscribed in a circle . The circle and the sequar is​

Answer 1

Answer:

98 cm²

Step-by-step explanation:

Given,

Radius of the circle =7cm

Let the side of the square be acm.

A square when inscribed in a circle then the diameter of the circle must be diagonal of the square.

Therefore,

Diagonal of square =a2+a2

                                 =a2

Now,

Diameter of the circle =2×7

                                  =14cm

=>2a=14

=>a=214

=>a=72cm

Therefore,

Area of square =a2

                       =(72cm)2

                       =(72cm)(72cm)

                       =98cm2
