Question

Don't give me the direct answer

anonymous · Answer

Sorry the Diameter of the circle is 6 in

anonymous · Answer

Write down the formula for finding the circumference of a circle using the diameter. The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi. Plugging π into your calculator will give you its numerical value, which is a closer approximation of 3.14.

I cant read some things on your post it shows up as ?

anonymous · Answer

sory..formula for circumfrnce is C=2*pi*R

if you know C=circumfrnce then find R and multiply it with 2 to get diameter...

anonymous · Answer

ok but I need a formula to help me find R

anonymous · Answer

sory..here r=radius not diameter..you are one step wrong..

anonymous · Answer

I guess your right. BUT can I at least get some help instead of no your wrong.

anonymous · Answer

you can find radius from here and then multiply it with 2 to get diameter..

anonymous · Answer

Never mind it is getting to complex. So I tried this and it worked 

Diameter = 6

$$6\div2=3^2=9$$

So my final thing was $$9 \pi ^2 $$ and it worked

anonymous · Answer

not 9pi^2

just 9pi

anonymous · Answer

For my answers I have to put 9pi^2

anonymous · Answer

no...its wrong..

anonymous · Answer

No its right I just got told it was right
