Question

The formula for the circumference of a circle is C = 2πr. Use this formula to write a formula for the RADIUS of a circle.

Answer 1

did not mean to close T_T

Answer 2

yes this is the formula for circumference of a circle

C = 2pir

so how you get from this isolate the r ?

Answer 3

ok.

than you divide both sides by 2pi what will get ?

Answer 4

idk

Answer 5

why ?

C/2pi = 2pir / 2pi

C/2pi = ?

Answer 6

what is pir

Answer 7

pi is 3,14 and r is the radius

Answer 8

pi*r

Answer 9

what is the radius

Answer 10

in your question of above wrote exercise there is RADIUS so this r is the radius noted

Answer 11

r is the radius of this circle with circumference C = 2pi*r

Answer 12

ok. ?

Answer 13

do you understand it now ?

Answer 14

yes

Answer 15

ok . was my pleasure

good luck

bye bye

Answer 16

or do you have questions ?

Answer 17

what answer?

Answer 18

what is the answer here ?

so given C = 2pi*r than you divide both sides by 2pi will get

C/2pi = 2pi*r/2pi

C/2pi = ?

Answer 19

do you see there on the right side will simplify the 2pi from numerator and denominator and will get the r what you need getting for right answer

ok. ?

Answer 20

ok

Answer 21

so than now is clearly sure for you - yes ?

Answer 22

yes ty

Answer 23

np

yw

anytime

bye bye
