Determine the mass of a solid steel ball that has a diameter of 10 cm. The density of pure steel is 8.09 g/cm3

Basile [38]

Answer:

<em>The mass of the steel ball is 4,235.9 gr</em>

Step-by-step explanation:

<u>Density</u>

The density ρ of a substance is a measure of its mass per unit volume:

$\displaystyle \rho=\frac{m}{V}$

If the density and the volume are given, the mass can be calculated by solving the above formula for m:

$m=\rho.V$

We know the density of pure steel ρ=8.09 gr/cm3 and the diameter of a solid steel ball d=10 cm.

We need to calculate the volume of the sphere:

The volume of a sphere of radius r is given by:

$\displaystyle V=\frac{4}{3}\cdot \pi\cdot r^3$

The radius is half the diameter: r= 10/2 = 5 cm. Thus:

$\displaystyle V=\frac{4}{3}\cdot \pi\cdot 5^3$

Calculating:

$V=523.6\ cm^3$

The mass is:

$m=8.09 gr/cm^3 \cdot 523.6\ cm^3$

m=4,235.9 gr

The mass of the steel ball is 4,235.9 gr

Students in Mrs. Walsh's math class wanted to know the favorite snacks of students in the school. How could they generate a rand

denis23 [38]

There are several ways this can be accomplished. Students could survey every 20 students until they've asked 100 students, or they could ask 1 or 2 people at each cafeteria table during each lunch, just for examples.

One high speed Internet provider has a $39 setup fee and charges $40 per month. Another

zvonat [6]

Answer:

2.1 months

Step-by-step explanation:

Let x represent the number of months

Set up expressions to represent the cost of each Internet provider

40x + 39 will represent the first one

30x + 60 will represent the other

Set these equal to each other and solve for x:

40x + 39 = 30x + 60

10x + 39 = 60

10x = 21

x = 2.1

So, the cost will be the same in 2.1 months
