Answer: C
Step-by-step explanation:
To find the surface area of a cone, you use the formula
. Since we are already given the height and radius, all we have to do is plug in the values and solve.
[solve inside of square root]
[parenthesis]
[multiply]

Therefore, the closest answer is C.
Answer:
The Correct option is Last one 
Therefore, equation of the line in slope-intercept that passes through (-2,4) and is parallel to the line
is 
Step-by-step explanation:
Given:

To Find:
Equation of line passing through ( -2, 4) and is parallel to the line y=-4x-3
Solution:
..........Given
Comparing with Slope-Intercept form,

Where m =slope
We get

We know that parallel lines have Equal slopes.
Therefore the slope of the required line passing through (-2 , 4) will also have the slope = m = -4.
Now the equation of line in slope point form given by

Substituting the points and so we will get the required equation of the line,

Therefore, equation of the line in slope-intercept that passes through (-2,4) and is parallel to the line
is

Answer:
90.3125 cm³
Step-by-step explanation:
Since the perimeter of the bottom square is 17, you can divide by four to find out what the lenght of each side is.
17/4=4.25 cm
We know the height of pyramid is 15 cm
The formula for the volume of a square pyramid is
V=a²(h/3)
V=a2(h/3)=4.252·15/3=90.3125 cm³
