Question

please help! how do you find radius?

Answer 1

the circumfrence is 6ft

Answer 2

Well you know that

\[\text{circumference} = 2\pi\times r\]

So given the circumference you need only divide both sides by 2pi to isolate the radius...and solve

so in your case

\[r = \frac{6ft}{2pi}\]

Answer 3

so its either a or c

Answer 4

Umm...I'm assuming that 'n' in their case must be a substitute for pi so I would go with C

Answer 5

okay thank you
