Answer:
704π m^2
Step-by-step explanation:
Given data
radius r= 16m
Slant height l= 28m
Required
The surface area of the cone
The expression for the surface area is given as
T.S.A=πrl+πr^2
substitute
T.S.A=π*16*28+π*16^2
T.S.A=448π+256π
T.S.A=704π m^2
Hence the T.S.A is 704π m^2

it's all in the pic
It should be the same, 25%. Let's say Josh makes $4,000 a year, and Jeff makes $5,000. Jeff makes 25% more than Josh, and Josh makes 25% less than Jeff. Hope this helped.
The given statement is true.
In general, the growth rate of exponential functions is far greater than the quadratic function. This can be illustrated through an example.
Consider an exponential function

and a quadratic function

.
Note that the leading coefficient of the quadratic function is far greater than the base of the exponential function but still the exponential function will exceeds the quadratic function after x = 15.664 as shown in the graph below.
Therefore, we can conclude that the given statement is correct.
Let us assume the two unknown numbers to be "x" and "y".
Then
x + y = 37
And
xy = - 210
x = - 210/y
Now let us put the value of "x" in the first equation, we get
x + y = 37
- (210/y) + y = 37
y^2 - 210 = 37y
y^2 - 37y - 210 = 0
y^2 - 42y + 5y - 210 = 0
y(y - 42) + 5(y - 42) = 0
(y - 42)(y + 5) = 0
So when
y - 42 = 0
y = 42
Then
x = -(210/42)
= - 5
Again when
y + 5 = 0
y = -5
Then
x = 42
So the two unknown numbers are 42 and -5. I hope the procedure is clear enough for you to understand.
