Question

the diameters of two silver discs are in the ratio 2:3 what will be the ratio of their areas

Answer 1

the ratio of their areas ---
$3.14 \times 2 = 6.28$
$3.14 \times 3 = 9.42$
so ratio is 6.28:9.42;-);-):O:O^_^^_^(^^)(^^)

Answer 2

(πD)/(πD) = 2/3
3(πD) = 2(πD)
(3πD) / (2πD)
3/2
the ratio of their areas is 3:2

this is your answer.......
