. A certain coin is a circle with diameter 18 mm. What is the exact area of either face of the coin in terms of p?

The area is given by:

And replacing we got:

So then we can conclude that the area of the coin is mm^2

Step-by-step explanation:

For this case we know that we have a coin with a diamter of , and by definition the radius is given by:

The area is given by:

And replacing we got:

So then we can conclude that the area of the coin is mm^2

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.
