A scoop of ice cream has a 3-inch diameter. How tall should the ice cream cone of the same diameter be in order to contain all o

pishuonlain [190]

Answer:

12 inches

Step-by-step explanation:

Suppose the ice cream scoop has the shape of a sphere of a radius (r) inches.

Thus, the top of the cone will also have a radius (r) inches.

Let consider h to be the height of the cone in inches.

So, the objective is to make the volume of the scoop of the ice cream to be the same as the volume of the cone.

To do that; we need to equate both volumes together and make h the subject of the formula:

The volume of a sphere = 4/3 πr³ and the volume of a cone = 1/3πr²h

4/3 πr³ = 1/3πr²h

Multiply both sides by 3

4πr³ = πr²h

4r = h

h = 4(3)

h = 12 inches

To contain all the ice cream inside the cone, the height of the ice cream cone needs to be 12 inches tall

A contractor is adding 243 CY backfill. If each truck can hold 162 CF, how many truck loads are needed

nexus9112 [7]

The number of trucks needed is an illustration of rates

The number of trucks needed is 42

<h3>How to determine the number of trucks</h3>

The size of the backfill is given as: 243 CY

A truck can load up to 162 CF

So, the number of trucks needed is calculated as:

$n = \frac{243 CY}{162 CF}$

Convert CY to CF

$n = \frac{243 * 27CF}{162 CF}$

Solve

$n = 40.5$

Approximate

$n = 41$

Hence, 41 trucks are needed
