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

Real number
<em><u>Step-by-step explanation:</u></em>
18.62 is a Real number. A real number is just a number that is either an integer, decimal or anything like that.
I think it’s B because it’s in the right for mate
Option A is correct.
Step-by-step explanation:
We need ti identify the radius of circle.
The radius of circle is a length of the line from center of the circle to anywhere on the edge of circle. It is also shown in the figure attached.
From the given options, only FE is the line that goes from center of circle to the edge of circle. So, FE is the radius of the circle.
So, Option A is correct.
