Question

The diameter of a circle is thrice the side of a square. The ratio of the area of the circle to that of the square is

Answer 1

Answer:

area of Circle/area of square =36×pie/1

Step-by-step explanation:

Area of Circle =pie × radius²

Area of Square = a²

we know that

radius r= diameter/2

given d= 3 a

so r/2= 3a

and r=6a

so

pie×r²=(r/6)²

=)pie×r²/r²/36=36×pie/1
