Answer:

a) i) 9:25

ii) 27:125

b) i) 7:9

ii) 343:729

Explanation:

Ratio of areas = (ratio of sides)²

= 3² : 5² = 9 : 25

Ratio of volumes = (ratio of sides)³

= 3³ : 5³ = 27 : 125

49 : 81 = ratio of areas

Ratio of sides = 49^½ : 81^½

= 7 : 9

Ratio of volumes = (ratio of sides)³

7³ : 9³ = 343 : 729
