Acone’s height and its radius are each equal to half the radius of a sphere. how many of these cones would it take to equal the volume of the sphere? a)16 b)24 c)32 d)48

  32

Step-by-step explanation:

Given: A cone’s height and its radius are each equal to half the radius of a sphere.

Let x be the radius of the sphere, then the radius of cone =x/2

and height of the cone = x/2

The volume of sphere is given by :

, where r is the radius of sphere.

The volume of cone is given by :

, where r is the radius and h is height  of the cone .

The number of cones would it take to equal the volume of the sphere is given by :-

452,489 to the nearest thousand is 452,000

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
