প্রশ্নে বলা হচ্ছে, একটি বৃত্তে একটি বর্গ অন্তর্লিখিত আছে। বৃত্তটির ব্যাস 10cm হলে বর্গটির ক্ষেত্রফল কত?

First, let us depict an inscribed square in a circle

As, radius of the circle is 10 cm

∴ Diameter $= 2 \times 10 = 20$ cm

Here, diameter of the circle will be the diagonal of the square.

So, the length of the diagonal = 20cm.

If 'a' is one arm of a square, then the length of the diagonal will be $a \sqrt{2}$

According to question, $a \sqrt{2} = 20$

$\Rightarrow a \sqrt{2} = 20 \Rightarrow a = \frac{20}{\sqrt{2}} ∴ a^{2} = {(\frac{20}{\sqrt{2}})}^{2} = \frac{400}{2} = 200 c m^{2}$

Therefore, area of the square is $200 c m^{2} .$ ans.

Differentiate financial and economic costs with suitable example. The total revenue (TR) and Average Cost (AC) functions of a firm are given by $T R = 4350 Q - 13 Q^{2} A C = Q^{2} - 5.5 Q + 150 + 675 Q^{2}$ Where Q refers to quantity of output. Find the profit maximizing level of output and maximum profit.
