Question

Suppose the diameter of a circle is
4

What is its circumference?

Answer 1

pi*the diameter is the circumference

Answer 2

^^^^^^^^^^^^^^^^^^

Answer 3

Do they want you to approximate pi? @patricks_girl2001

Answer 4

\(\sf C = \pi d\)

Where 'd' is the diameter.

Answer 5

i don't know thats why I'm confused @iGreen

Answer 6

Okay, do you have options?

Answer 7

3.14 * 4???? @iGreen

Answer 8

Yes!

Answer 9

Ok very easy! pi*the diameter is the circumference, diameter = 4. so x the = 12.57 would be the circumfence. The area of a circle is D = π x r x r where r = radious of the circle

So 4π = π x r x r
4 = r x r
r = 3

Circumference of a circle is C = π x D where D is Diameter of the circle
C = π x 2 x r
= π x 2 x 3 = 12.57π Answer
Hope this helps! If you have anymore tag me on them! Have a nice day.
(12.57 Is your answer)

Answer 10

Just multiply that.

Answer 11

@DatChinookGuy Nice job, but we need the asker's participation.

Answer 12

i don't get this i press hint and i got the same answer ad u guys @iGreen and @DatChinookGuy but it gave me 4?!

Answer 13

It gave you \(\sf 4 \pi\), not \(\sf 4\).

Answer 14

Which is the exact measurement of the circumference.
