Question

the circumference of two circles are in ratio 3:4 . find the ratio of their areas ​

Answer 1

Step-by-step explanation:

i have attached the answer

Answer 2

Answer:

9/16

Step-by-step explanation:

let the radius of first circle be r1and the radius of second circle be r2

circumference of first circle is 2πr1

and

circumference of second circle is 2πr2

according to the question

2πr1/2πr2 = 3/4

r1/r2 = 3/4

let r1be 3x and r2 be 4x

area of first circle = π(r1)^2

area of second circle is = π(r2)^2

ratio of areas = π(r1)^2/π(r2)^2

= (3x)^2/(4x)^2

= 9/16

ratio of area of circle = 9/16

hope this will help u
