Ratio of area of a circle to the area
Question:

Ratio of area of a circle to the area of a square whose side equals radius of circle, is 1 : TC.

Solution:

False

Given, side of a square equals radius of a circle.

Then, area of the square = r2

and area of the circle =πr2

where r is a radius of the circle.

Now, the ratio of area of the circle to area of the square = πr2: r2  = π : 1.
