I need help finding the circumference, I have my notes, and all that, but Idk- I'm just slow when it comes to math, I just don't understand it, also my teacher isn't here we have a sub and I kinda forgot how to do it. (IT is NOT a test.) (Ss below)
I need help with 1, Please don't give the answer, I just don't understand how to set it up.
Would you rather have an example or the formula?
So, both alright, give me a second to put the formula down.
\[C=2\pi r\] So an Example would be, Say radius=8 |dw:1620838908985:dw| As radius equals 8, you need to divide it by two because you need the half- radius, not the full thing. So, it turns into 4. Because: \[8\div2=4\] &/or \[8\times0.5=4\] So, when trying to find the circumference, you: \[C=2\pi r\] Install the r, as r=4 \[C=2\pi (4)\] Now, install that in a calculator; \[C=2\pi(4)=25.1\] Now, the question is solved! \[C=25.1\] 𝙸 𝚑𝚘𝚙𝚎 𝚝𝚑𝚊𝚝 𝚝𝚑𝚒𝚜 𝚐𝚒𝚟𝚎𝚗 𝚒𝚗𝚏𝚘𝚛𝚖𝚊𝚝𝚒𝚘𝚗 𝚑𝚊𝚜 𝚑𝚎𝚕𝚙𝚎𝚍 𝚘𝚛 𝚊𝚒𝚍𝚎𝚍 𝚢𝚘𝚞𝚛 𝚔𝚗𝚘𝚠𝚕𝚎𝚍𝚐𝚎 𝚓𝚞𝚜𝚝 𝚊 𝚋𝚒𝚝; 𝙲𝚘𝚗𝚝𝚊𝚌𝚝 𝚖𝚎 𝚒𝚏 𝚢𝚘𝚞 𝚗𝚎𝚎𝚍 𝚊𝚗𝚢𝚝𝚑𝚒𝚗𝚐 𝚎𝚕𝚜𝚎... @𝙸𝚖𝚊𝚐𝚒𝚗𝚎
Thank you, This Helps quite a bit.
@imagine radius is already half, it's if you have diameter, you want to cut it in half and find radius So if you had a radius of 8, it would just be 8(pi)(2)
Yeah, I had forgotten the term for a full radius. Thanks Snow.
