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:

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

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:

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

Calculating:

The mass is:

m=4,235.9 gr
The mass of the steel ball is 4,235.9 gr
Answer:
6(2x+3)
Step-by-step explanation:
12x +18
Factor out 6 from each term
6*2x+ 6*3
6(2x+3)

Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Range is the least number (50) subtracted from the greatest number (90)
90-50 = 40 (range)
The most dots is at 70 and the chart is symmetrical.
The correct answer would be A.36.
Hope this helps;)
