Question

Help?!?! You can have a medal!

Answer 1

here is the review

Answer 2

you wouldnt by chance know how to solve these two? @qdbug

Answer 3

no nowhere near that

Answer 4

@TheOcean

Answer 5

oh well i just did that on angles. i didnt realize those were circles. lol sorry. i just had a major brainfart. maybe you can look up 'How to calculate pi of circles'

Answer 6

you kno how to solve it? @TheOcean

Answer 7

oh thats ok, thx anyway

Answer 8

@TheOcean

Answer 9

pi always equals 3.14

Answer 10

I know that @CelesteSelene13

Answer 11

@dan815

Answer 12

okay so some basics, like you know that there are 360 degrees in a circle

Answer 13

yes...we can skip the basics I'm in high school

Answer 14

okay well do you know how many radians 360 degrees are

Answer 15

u mean like how many radii complete a circle?...My teacher taught us there are infinite radii and diameters

Answer 16

radians are another measure for angle, instead of in degrees its the more natural way

Answer 17

there are 2 pi radians in every circle

Answer 18

ummm we i dont think we have learned that.....

Answer 19

if you multiply this measure of angle radians by the radius you will get the real arc length or the circumference anything u want

Answer 20

you have, like you know circumference is 2*pi * r

Answer 21

ohhhh yea ok, yes....

Answer 22

I get that

Answer 23

that is the cae because there are 2*pi radians in a circle

Answer 24

okay now lets see how big the arc could be for 72 degrees for your given problem

Answer 25

lets do it a simple intuitive way if radians confuses you for now

Answer 26

ok so would u take 360 - 72?

Answer 27

whats the circum?

Answer 28

it is 157.1 approx

Answer 29

ok its working now

Answer 30

are you good with these 2 questions now?

Answer 31

I think so! thank you very much! are this good at biology as u r at math?

Answer 32

I have to go...but when I'm back later would u mind if I tagged u with some problems?.... @dan815

Answer 33

if ur online

Answer 34

no lol i dont know anything about biology not even the slightest

Answer 35

oh ok well thank you very much for the math help!!! @dan815
