Question

The ratio of radii of the two circles is 3:5. Find the ratio of their areas

Answer 1

$\mathfrak\orange{Hey\: mate....here's\: ur\: answer...}$

Ratio of the two circles radii = 3:5

Let their radii be 3x and 5x...

Therefore,

Area of 1st circle = pi(3x)^2 = pi×9x^2

Area of 2nd circle = pi(5x)^2 = pi×25x^2

Ratio of their area = (pi × 9x^2)/(pi × 25x^2)

=> 9 : 25
