Question

The circumference of two circles are in tha ratio 3:1then the ratio of their areas will be

Answer 1

★ GEOMETRY [ CIRCLES ] ★

Given that the ratio of circumference of two circles is 3:1

Let the radius of two circles be m and n

2πm : 2πn = 3 : 1

Hence, m : n = 3 : 1

Ratio of areas of the circles will be ,

2πm² : 2πn² = m² : n² = 9 : 1
