Answer:
use area
Step-by-step explanation:
we can't use volume here since we are dealing with the outside part only
so area of a cylinder is =πr²h
our r represents the radius which is diameter/2
r=7.5/2
=3.75m
our h represents height which is 12.5m
so put in our formula
area = π×(3.75)²×(12.5)
=552.2330836m³
that's it dear

The slope-intercept form of a line is:
y = mx + b
Where m is the slope and b is the y-intercept.
Two lines having slopes <em>m1</em> and <em>m2</em> are perpendicular if
m1 * m2 = -1
We are given the equation of one line:
It's required to find the equation of another line that is perpendicular to it. We have m1 = 1/3, let's find the other slope:
The slope of the required line is -3. Now we use the point through which the line passes (-2, 2).
We use the point-slope form of the line:
y - k = m( x - h)
Where (h,k) = (-2, 2) is the point. Substituting:

Answer:
-16
Step-by-step explanation:
Let's call the number x. Double the sum of x and seven is 2(x + 7) and two less than x is x - 2. Since these are equal we can write:
2(x + 7) = x - 2
2x + 14 = x - 2
x = -16
Answer:
Domain : { -3, 0, 3}
Range : { 1 , 1 , 1 }
Function : These set of ordered pairs are functions as every x-value has only one y-value associated with it.
