14α - (2a + 9) = 3 (12a - 18)

Leona [35]

Answer:

a = 2 5/8

Step-by-step explanation:

14a - (2a + 9) = 3 (12a - 18)

14a - 2a + 9 = 36a - 54

12a + 9 = 36a - 54

12a - 36a = -54 - 9

-24a = -63

a = -63/-24

a = 21/8

a = 2 5/8

For cylinders to be similar, the ratio between their height and radius must be equal.Our cylinder's ratio is :
$\frac { length }{ radius } =\frac { 15 }{ 3 } \\ =5$

The only cylinder with same ratio is the one at the choice B.

$\frac { length }{ radius } \frac { 25 }{ 5 } =5$
