What is the slope of the line that is perpendicular to the line whose equation is 2x + y = 4.

The slope of the line that is perpendicular to the line whose equation is 2x + y = 4 is   .

Step-by-step explanation:

Given : Equation is 2x + y = 4.

To find : What is the slope of the line that is perpendicular to the line.

Formula used : equation of line y =  m x + c.

Solution : We have 2x + y = 4.

Rearranging the equation :  y = - 2x + 4.

On comparing   m = - 2.

Condition for  slope of the line that is perpendicular to the line :

      m × m = -1 .

So,       -2 × m = -1 .

On dividing by 2 both we get ,

  m = .

Therefore, The slope of the line that is perpendicular to the line whose equation is 2x + y = 4 is   .

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.
