It’s the last one because when when it’s a equal to the circle is always closed and it says it has to go that way so it’s the last one

Answer

Find the volume of the coin is cubic millimeters.

To prove

Formula

$Volume\ of\ cylinder\ = \pi r^{2} h$

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.

$Radius = \frac{Diameter}{2}$

$Radius = \frac{26.5}{2}$

Radius = 13.25 mm

$\pi = 3.14$

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 .
