Answer:
Step-by-step explanation:
<u>Formula for circumference of a circle is</u>:
Circumference = 
<em>Given circumference of the ring is 
</em>
<em>Now solving for the radius gives us:</em>
We know that area of a circle is 
, substituting the value of r we found, we get the area as:
area (A) = 
Hence the Area (A), in terms of 
is 
A quics way to do this :-
9C5 = 9*8*7*6*5 3 * 7 * 6 = 126
------------- =
5*4*3*2*1
Answer:
-7
Step-by-step explanation:
6x - 5 = -47 subtract 5 from both sides so the x is alone
6x = -42 divide by 6 so you can find what x equals
x= -7
Could you type out the questions because the picture is blurry and hard to read
6 times (2/8)+ 6(5/8)
12/8+ 30/8= 42/8
