How do you find the circumfrence and area of a circle? Examples please or a link to a website.

Answers

Area or a circle
A= 3.14 (pi) multiplied by the radius to the second power
So if a circles radius is 3 cm it would be pi multiplied by 9 which equals 28.27 cm2
Circumference
C= pi multiplied by the diameter

To find the corcumference of the circle the formula is 2(pi)r
to find the area of the circle the formula is (pi)(r)(r)

What is 3.25 with the 5 repeating as a rational number

Answers

So,

$3.2\overline{5}$

Multiply it by 100.

$3.2\overline{5}--\ \textgreater \ 325.5\overline{5}$ .

We now know that $325.5\overline{5}$ is 100 times of $3.2\overline{5}$ . If we subtract the first from the second, we will get 99 of the number. Then, we can simply divide by 99 and we will have it in fraction form.

$325.5\overline{5}-3.2\overline{5}=322.3$

Now, we put it over 99.

$(322.3)/(99)$

Of course, we cannot have decimals in fraction form, so we will just fix that.

$(3223)/(990)= (11*293)/(2*3*3*5*11)=(293)/(2*3*3*5)=(293)/(90)\ or\ 3 (23)/(90)$

322 over 99 is your answer. Hope this helps!
