Answer:

2660.94km³

Step-by-step explanation:

the volume V of a cylinder is given by πr²h, where r is the radius and h is the height and π = 3.1416

r = diameter/2 = 22/2 =11km

V = 3.1416 * 11² * 7 = 2660.9352 km³

V = 2660.94km

Which of the following equations is equivalent to log(y)= 3.994 ?

horrorfan [7]

Answer:

The correct answer is option D: $y = 10^{3.994}$

Step-by-step explanation:

Given:

log(y)= 3.994

Solution:

A logarithm base b of a positive number x satisfies the following definition:

$y =log_b(x) => b^y =x$

For $x > 0, b >0, b \neq 1$

Also if no base b is indicated, the base of the logarithm is assumed to be 10 .

Thus, in log(y)= 3.994 base b is not indicated. so its base is assumed to be 10

now

$log_{10}(y)= 3.994$

Then

$y = 10^{3.994}$

First you wanna distribute the 3 to x and 4
So the problem will then be 3x+12= 27
Then you wanna subtract 12 from 27
You get 3x = 15
Now you wanna divide 3x and 15 by 3
You then get X = 5
