Step-by-step explanation:
Diameter=24 in
Radius=12 in
Height=30 in
volume of the cone = 1/3πr²h
= 1/3(12)²×30π
= 1440 π in³
Answer:
$8.07
Step-by-step explanation:
20-((5*1.59)+3.98)=8.07
To find the slope of the perpendicular line, you can take the negative reciprocal of the slope of the line it is perpendicular to.
Taking the negative reciprocal of -1/5 gives 5.
Now we have y=5x+b, where b is the y-intercept. Since we know that the perpendicular line passes through the point (1,4), we can substitute those values into the equation we have to find b.
y=5x+b
4=5(1)+b
4=5+b
b=-1
Therefore, the equation of the perpendicular line is y=5x-1.
