Do you know how to find the circumference?
OpenStudy (shamim):
Circumference=2*pi*r
OpenStudy (anonymous):
I believe Pi = 14 correct??
Mehek (mehek14):
pi = 3.14

Mehek (mehek14):
and it goes on but you can use just 3.14
OpenStudy (anonymous):
oh yeah lol forgot the 3
OpenStudy (triciaal):
the circumference in terms of Pi means leave pi as pi
OpenStudy (anonymous):
yeah let me get a pen lol
Mehek (mehek14):
you don't need a pen to find the radius...it's already there

Circumference = 2*pi* r
r = 15
C = 2*pi* 15
C = 30 pi

i got 94.2 but i dont think thats correct
Mehek (mehek14):
94.2 for the radius??
OpenStudy (anonymous):
no, i got 94.2 as circumference
Mehek (mehek14):
you have to leave pi by itself

for the radius I got 30
OpenStudy (triciaal):
@shamim C = 2 Pi r
Mehek (mehek14):
30 would be the diameter
Mehek (mehek14):
radius = \(\dfrac{diameter}{2}\)
OpenStudy (anonymous):
15

is the radius
OpenStudy (triciaal):
@LetsLearn2000 please read the original question again
Mehek (mehek14):
ok so plug in 15
\(2π15\)
Mehek (mehek14):
now all you have to do is multiply \(2*15\)
Don't do anything to pi
OpenStudy (anonymous):
30

Mehek (mehek14):
ok so you have \(30π\)
Mehek (mehek14):
That should be your final answer since you keep pi as it is
OpenStudy (anonymous):
Ok so i got all the way up to here. I did 30 x Pi and got 94.2
OpenStudy (anonymous):
oh ok i see now.
OpenStudy (anonymous):
thanks !

your question states
What is the circumference of the given circle in terms of Pi.
meaning just leave pi with the answer
Mehek (mehek14):
yw \(\ddot\smile\)
