Question

Find the value of the circumference of a circle with the given diameter.

3.21 ft.

C =
A = 1.61 pi
B = 3.21 pi
C = 6.42 pi

Answer 1

5.03 ft

Answer 2

The equation for circumference is\[C=2\pi r\]

So just plug in 3.21 ft and calculate it

Answer 3

Well you have to divide 3.21 ft by 2 first, since you're given diameter and need the radius for the equation

Answer 4

C=8.08 ft

Answer 5

but my answer is suppost to have pie in it

Answer 6

then is 2.57 pie

Answer 7

c=π.d

Answer 8

d=2r

Answer 9

2.57 is not one of my answers

Answer 10

then the correct answer is c which equal=6.42 pi

Answer 11

the answer is C

Answer 12

thank you all for the help

Answer 13

The answer should be B.

The diameter is 3.21.

\[C=2 \pi r \rightarrow C=D \pi\]

D=3.21

So,

\[C=3.21 \pi\]

Which is B

Answer 14

oh. your right. i checked and the answer was b. thanks

Answer 15

No problem!
