Question

The circumferenc of two circle are in the ratio of 2:3. Find the ratio to their areas

Answer 1

Answer:

The answer is 4:9.

Step-by-step explanation:

let the radius of circles be R1 and R2.

and put the value in the formula,

circumference of the first circle upon circumference of the another circle

as 4πR.

Answer 2

Given:

• Circumference of two circle are in ratio of 2:3

To Find:

• Ratio to their areas = ?

Solution:

(r1/r2)= 2/3(r1/r2)^2

= 4/9(pi*r1^2/pi*r2^2)

= (4/9)A=pi*r^2(A1/A2)

=(4/9)

Ratio to their areas = 4:9
