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 .

Find the volume of these solid<br><br>20mm<br>3.7mm<br>41mm​
Reil [10]

The volume of the solid is which is a cone is 100.48 km^{3}.

Given a cone of radius 4 km and height being 6 km.

We are told to find the volume of the cone.

Volume is basically the amount of a substance that a container can hold in its capacity.Its value cannot be equal to zero or negative. It is basically amount of filling in a container.

Volume of cone is 1/3 \pi r^{2} h.

Volume =1/3 \pi 4^{2} *6

=1/3 π*16*6

=32π

=32*3.14

=100.48km^{3}

Hence if the radius of the cone is 4 km and height be 6 km then the volume of the cone is 100.48km^{3}.
