How do I solve a+18=7a ?

Slav-nsk [51]

$a+18=7a \ \ \ |\hbox{subtract 7a from both sides} \\
-6a+18=0 \ \ \ |\hbox{subtract 18 from both sides} \\
-6a=-18 \ \ \ |\hbox{divide both sides by (-6)} \\
a=3$

3 in. × 4 in. = 12 in.²

A = πr²

A = 12.57 in.²

12.57 in.² ÷ 2 = 6.285 in.²

6.285 in.² + 12 in.²

18.285 in.²
