Ore is a mineral that is a deposit in the earth's crust, of one or more valuable minerals. The most important as well as valuable ore deposits contain metals crucial to industry as well as trade, like copper, gold, iron and the like. Copper ore is mined for various industrial uses.

The formation of ore happens when magma or lava cools. This cooled magma has ore within it, which is carried to crystallize in order to form tiny minerals in the newly-created igneous rock. The minerals found in such rocks include feldspar or mica.

Answer:

D). $\frac{3}{2} \pi\: units^2$

Explanation:

Let the $m\angle BOC = x\degree$

$\therefore m\angle AOB = 2x\degree$

$\because m\angle AOB+m\angle BOC = 180\degree\\..(straight \: line \: \angle 's) \\\therefore 2x + x = 180\degree \\\therefore 3x = 180\degree \\\\\therefore x = \frac{180\degree}{3}\\\\\therefore x = 60\degree \\\therefore 2x= 2\times 60\degree = 120\degree \\\implies m\angle BOC = 60\degree \\\therefore central \: \angle \: (\theta) = 60\degree \\Radius\: of \:circle \: (r) = 3\: units \\\\Area \: of\: shaded \: region\\\\ = \frac{\theta}{360\degree}\times \pi r^2 \\\\= \frac{60\degree}{360\degree}\times \pi \times 3^2 \\\\= \frac{1 }{6}\times \pi \times 9 \\\\= \frac{1 }{2}\times \pi \times 3 \\\\\huge \purple {\boxed {= \frac{3}{2} \pi\: units^2}} \\\\$
