Question

The diameter of this circle is 5 when i sloved for the ci,. of the circle i got 15.70 am i right

Answer 1

no c=pie r^2
so your answer should be 19.63 (rounded)

Answer 2

wait lol so you are saying C= pie times the radius times two ? http://www.helpingwithmath.com/printables/worksheets/geo0701circle01.htm this is the sheet i am working on i think i geting what yuh sayying mixed up?

Answer 3

no.. could you google equation of a circumference.? if it says pie r^2 ur supposed to half the diameter, then square the halfed diameter when doin ure equation

Answer 4

ommg i still dnt get it but thx anyy way roc.

Answer 5

um lets see if the equation of the circumference is 2Pir then since you're using the radius you have to half the diameter.. so you can square your radius and times it bye pie

Answer 6

1st whats 2Pir and radius is half of the dia.

Answer 7

just nvm i will just google cuz i dnt think i am explaing it right but thx

Answer 8

yes it is so once you get your radius all you need to do is square it, then multiply by 5
and 2pir is square root, then times by pie

Answer 9

thx

Answer 10

wait so letsthe raduis was 5 and the dia is 10 i just mtiply that by 3.14 right ?
