Twenty-seven solid gold spherical beads each of radius 3 are melted down and recast into a larger, solid gold sphere. How many u

Mnenie [13.5K]

<h3>Answer: 9 units</h3>

===================================================

Explanation:

Let's calculate the volume of one small spherical bead

V = (4/3)*pi*r^3

V = (4/3)*pi*3^3

V = 36pi

The volume of 27 such identical beads is 27*36pi = 972pi cubic units.

----------

This is the new volume and we'll use this to find the radius r of the larger sphere.

V = (4/3)*pi*r^3

972pi = (4/3)*pi*r^3

3*972pi = 4pi*r^3

2916pi = 4pi*r^3

r^3 = (2916pi)/(4pi)

r^3 = 729

r = (729)^(1/3)

r = 9 units is the radius of the larger gold sphere

Jlenok [28]

Answer:

He have left 1250 milliliters of sport drink.

Step-by-step explanation:

Given:

Eduardo bought 2 litre sports drink for soccer practice during practice.

Eduardo drank 250 milliliters of sport drink then he drank another 1/2 liter.

Now, to find the milliliter of sport drink he have left.

Eduardo bought sports drink = 2 litre.

Now, to convert litre into milliliter by using conversion factor:

1 litre = 1000 milliliter.

2 liters = 2 × 1000 milliliters.

2 liters = 2000 milliliters.

Thus, Eduardo bought 2000 milliliters sport drink.

As, Eduardo drank 250 milliliters of sport drink.

So, to get the sport drink left after he drank we subtract 250 milliliters from 2000 milliliters:

$2000-250\\\\=1750\ milliliters.$

Thus, 1750 milliliters sport drink left.

Now, to get the sport drink left after he drank $\frac{1}{2} \ liter$ we subtract $\frac{1}{2} \ liter$ from 1750 milliliters:

$\frac{1}{2} \ liter =500\ milliliters.$

So,

$1750-500\\\\=1250\ milliliter.$

Therefore, he have left 1250 milliliters of sport drink.
