Question

The radii of the two circular field is in the ratio 3 : 5. The area of the first field is

what percent less than the area of the second?​

Answer 1

Answer:

as we know

$\pi R1^{2} =\pi R2^{2}$

Step-by-step explanation:

$\pi (3x^{2}) =\pi (5x^{2})$

now take ratio

Answer 2

Step-by-step explanation:

πR12=πR22

Step-by-step explanation:
