Find the approximate area of the shaded region below, consisting of a right triangle with a circle cut out of it. use 3.14 as an approximation.

an image shows a right triangle with a circle cut out of it. the legs that make up the right triangle are both 60 meters. the diameter of the circle cut out is 20 meters.

Answer

Find the volume of the coin is cubic millimeters.

To prove

Formula

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 = 13.25 mm

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 .
