. 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?

vitfil [10]

Answer:

$r =\frac{D}{2}=\frac{18mm}{2}= 9mm$

The area is given by:

$A= \pi r^2$

And replacing we got:

$A=\pi (9mm)^2 =81\pi mm^2$

So then we can conclude that the area of the coin is $81\pi$ mm^2

Step-by-step explanation:

For this case we know that we have a coin with a diamter of $D =18mm$ , and by definition the radius is given by:

$r =\frac{D}{2}=\frac{18mm}{2}= 9mm$

The area is given by:

$A= \pi r^2$

And replacing we got:

$A=\pi (9mm)^2 =81\pi mm^2$

So then we can conclude that the area of the coin is $81\pi$ mm^2

14 POINTS + Brainliest to first correct answer with explanation and diagram.

zhuklara [117]

So for example we have

1/2 divided by 1/6

What we will do it’s

Leave the first one As it is

Turn the second fraction (the one you want to divide by) upside down

The change the divide to multiply

Multiply the first fraction by that reciprocal

Simplify the fraction (if needed)

So it’s will be like this

1/2 x 6/1 = 6/2

Simplify it

6/2 =3

I hope it’s will help u ✨
