Question

if the circumference of a circle is equal to the perimeter of a square, then what will be the ratio of their areas?
​

Answer 1

Answer:

π:a^2

Step-by-step explanation:

Let the radius of the circle be a.

Circumference= 2πa

Let the side of the square be a.

Perimeter of the square= 4a

Area of the circle= πa^2

Area of square= a^4

Ratio= πa^2/a^4

=π/a^2
