of the circumference of two circles is 4: 1. Find the ratio of their areas.​

Answer 1

Answer:

16:1

Step-by-step explanation:

let, radius of the 2 circles be r and R.

ratio of circumference = 2πr : 2πR = 4:1

=> r:R = 4:1

let, r be 4x and R be x

ratio of areas = πr² : πR²

= r² : R²

= 16x² : x²

= 16:1
