Given:
The equation of a line is
...(i)
The perpendicular line passes through the point (-1,4).
To find:
The equation of the perpendicular line.
Solution:
The slope intercept form of a line is:
...(ii)
Where, m is the slope and b is the y-intercept.
On comparing (i) and (ii), we get
Product of slopes of two perpendicular lines is -1.
Let the slope of perpendicular line is 
.
The slope of the perpendicular line is and it passes through the point (-1,4). So, the equation of the line is:
Add 4 on both sides.
Therefore, the equation of required line is .
The answer is 21.2 ft²
To do this we need to calculate the volume of the cylinder shaped drum.The volume (V) of the cylinder with height h and radius r is:V = π r² h
We have:π = 3.14r = 1.5 fth = 3 ft
Therefore:V = π r² hV = 3.14 * (1.5 ft)² * 3 ftV = 21.2 ft²
here you go
That would be A. SSS postulate because it tells you that all three sides and corresponding sides are congruent.
Answer: Radius = volume 18 ft
Diameter = volume 22.5 ft
Area of base = volume 20 ft
