Answer:
1005.3 cm³
Step-by-step explanation:
The radius of the cone (r) is 8 cm and the slant height is AC = AB = 17 cm.
Therefore, the height of the cone (h) will be given by cm.
We have to calculate the volume of the cone.
Therefore, the volume of the cone will be given by
=
= 1005.3 cm³ (Answer)
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
