Q2. Calculate the number of complete squares inscribed in a circle
Ans. 
The number of complete squares inscribed in a circle can be calculated using a formula based on the number of sides of the square.
• The formula to calculate the number of complete squares inscribed in a circle is n*(n+1)*(2n+1)/6, where n is the number of sides of the square.

• For example, if the circle has a square with 4 sides inscribed in it, the number of complete squares would be 30 (4*(4+1)*(2*4+1)/6 = 30).
