Answer 1

It’s 9. 3x9 is 27. Nothing else times anything equals 27, excluding decimals.

Answer 2

Answer:

3 in²

Step-by-step explanation:

The linear ratio = 3 : 1, hence

The area ratio = 3² : 1² = 9 : 1

let x be the area of the smaller circle, then

$\frac{9}{1}$ = $\frac{27}{x}$ ( cross- multiply )

9x = 27 ( divide both sides by 9 )

x = 3

Area of the smaller circle = 3 in²
