Question

69. The ratio of the volumes of two
spheres is 8:27. The ratio between
their surface areas is *
O 1)2:3
2) 4:27
)
O 3) 8:9
O 4)4:9​

Answer 1

Step-by-step explanation:

Let radius be r and R respectively

4/3πr³

____. = 8/27

4/3πR³

r³/R³ = 2³/3³

r/R = 2/3

Ratio of surface area = 4πr²/4πR²

= r²/R²

= 2²/3²

=4/9 = 4:9
