A scoop of ice cream has a 1.5 inch radius. How tall is the ice cream cone of the same radius be in order to contain all of the ice cream inside the cone

  6 inches

Step-by-step explanation:

The formula for the volume of a sphere is ...

  V = (4/3)πr^3

The formula for the volume of a cone is ...

  V = (1/3)πr^2h

The volumes will be equal when their ratio is 1:

  (4/3πr^3)/(1/3πr^2h) = 1

  4r/h = 1 . . . . simplify

  4r = h = 4(1.5 in) = 6 in . . . . . multiply by h, substitute given values

The height of the cone must be 6 inches to hold the volume of the spherical scoop of ice cream.

up

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
