Answer:
$22,968
Step-by-step explanation:
To solve this question, we need to find the volume of the cylinder. Let’s call this V
Mathematically V = πr2h
where r = 3m , h = 7m and π = 22/7
Putting this in the formula:
V = 22/7 * 3 * 3 * 7 = 198 cubic meter
We are told concrete costs $116 per cubic meter. Hence, for 198 cubic meter we have 198 * 116 = $22,968
Answer:
log(0.0003) = -3.5229
Step-by-step explanation:
The rules of logarithms tell you ...
log(ab) = log(a) +log(b)
<h3>Application</h3>
log(0.0003) = log(3×10^-4) = log(3) +log(10^-4)
= log(3) -4 = 0.4771 -4
log(0.0003) = -3.5229

<em>Additional comment</em>
If you do much work with logarithms, you find that negative logarithms are generally expressed using a positive mantissa with a negative add-on. Often, that negative add-on is -9, so this would be ...
5.4771-9
This helps when taking antilogs, as you look up 0.4771 in the table to see that the multiplier is 3.
If you were to look up 0.5229, you would find 3.333, meaning the multiplier is 1/3.333 and the antilog of -3.5229 is (10^-3)/3.333. This may not be a convenient value to work with.
