Answer
Find the volume of the coin is cubic millimeters.
To prove
Formula
[tex]Volume\ of\ cylinder\ = \pi r^{2} h[/tex]
Where r is the radius and h is the height .
As given
The $1 coin depicts Sacagawea and her infant son.
The diameter of the coin is 26.5 mm, and the thickness is 2.00 mm.
[tex]Radius = \frac{Diameter}{2}[/tex]
[tex]Radius = \frac{26.5}{2}[/tex]
Radius = 13.25 mm
[tex]\pi = 3.14[/tex]
Put in the formula
Volume of coin = 3.14 × 13.25 × 13.25 × 2.00
= 1102.53 mm³ (approx)
Therefore the volume of the coin is 1102.53 mm³ .
