Answer:

A) Volume of the pile of sand is 2411.7 in³ .

Step-by-step explanation:

Given : A pile of sand on the beach has the approximate shape of a cone with a diameter 28 in. and a height of 11.75 in.

To find : volume of the pile of sand.

Solution : We have given that diameter of cone  = 28 in.

                                                  height = 11.75 in.

Radius =  \frac{diameter}{2}.

Radius = 14 in.

Volume of cone  = \frac{pi(radius)^{2}*height }{3}.

Volume of cone =  \frac{3.14(14)^{2}*11.75 }{3}.

Volume of cone  = 2410.47

Volume of cone ≈ 2411.7 in³.

Therefore, A) Volume of the pile of sand is 2411.7 in³ .

Find an equation of the perpendicular bisector of the line segment whose endpoints are given.
REY [17]

Answer:

The equation of the perpendicular bisector line

5 x - 2 y + 31 =0

Step-by-step explanation:

<u><em> Explanation:-</em></u>

Given points are ( 0,1) and (-10,5)

The Midpoint of given two points

             (\frac{x_{1}+x_{2}  }{2} , \frac{y_{1}+y_{2}  }{2} )

             (-5 , 3)

The Slope of the line

 m =        \frac{y_{2} -y_{1} }{x_{2}-x_{1}  } = \frac{5-1}{-10} = \frac{-2}{5}

The perpendicular slope

    =   \frac{-1}{m} = \frac{-1}{\frac{-2}{5} } = \frac{5}{2}

The equation of the perpendicular bisector line

 y - y_{1} = m (x - x_{1} )

 y - 3 = \frac{5}{2} ( x-(-5))

  2 y - 6 = 5( x +5)

    5 x + 25 -2y +6 =0

   5 x - 2 y + 31 =0
