Answer:
Surface area = 4 π r2 square units
Step-by-step explanation:
Let's consider that number to be 'x'..
So, twice the number (2x) is 12 greater than than the half of the number.
So the equation will be like,
2x=12+x/2
Solving this further,
2x=(24+x)/2
=> 4x=24+x
=>4x-x=24
=>3x=24
=>x=8..
So the number is "8".

Answer:
$20.16
Step-by-step explanation:
First we need to find 12% of his current hourly rate, 12% is our decimal multiplier here so we use 0.12. In order to get 12% we need to multiply our decimal by $18 which is:
$18 × 0.12 = $2.16
Now let's add this 12% on top of his current hourly rate.
$18 + $2.16 = $20.16
And that's the final answer.
