Question

What is the circumference of a circle with a diamter of 2?

Answer 1

do you know the formula for the circumference of a circle?

Answer 2

Yes, 3.14 times the radius or diameter, correct?

Answer 3

yes - which one is it - do you know?

Answer 4

2pi

Answer 5

lol

Answer 6

Since it's the diameter I don't have to multiply by two, so just 2(3.14)?

Answer 7

circumference=2 pie r
we will take r=d/2
it will be2/2=1
now put the values 2*3.14*1=6.28
*pie=3.14

Answer 8

the standard formula is:\[C=2\pi r\]where C is the circumference and r is the radius.
now, since the diameter is equal to twice the radius, then we can also write:\[C=2\pi r=\pi d\]where d is the diameter

Answer 9

or just 6.2830 blahblahblah
