Answer:

easy peasy  lemon squeasy (l o l)

Step-by-step explanation:

let the radius of one circle be r and the other be R,

there fore,

2πr + 2πR = 80

=> 2π( r + R) = 80

but we know that, R =2r

=> 2 π ( 3r) = 80

=> 3r = 40/π

=> r = 40/3π

taking the value of pi to be 3.14

=> r = 40/9.42

=> r = 4.246

hence the larger radius = 2r => 8.492
