Question : 68 of 100

Marks: +1, -0

What is the area of the square (in

{cm}^{2}

) whose vertices lie on a circle of radius

5 {cm}

Solution:

Given,
Radius of Circle

=5 {cm}

We know that,
Side of square

=\;{\;\text " Diameter "\;}/{√{2}}=\;{10}/{√{2}} {cm}

[ ∵

Diameter

=2 ×

radius

]

So, area of square

=(\;\text " side "\;)^{2}

=\;{10}/{√{2}} × \;{10}/{√{2}}=\;{100}/{2}=50 {cm}^{2}
