Question

A circular swimming pool has a diameter of 12 m.



What is the approximate circumference of the swimming pool?
Use π= 3.14.
Express your final answer to the nearest hundredth.

Answer 1

I'm thinking 37.68. \[3.14 \]

Answer 2

3.14 x 12

Answer 3

Answer 4

C = 2pir? \[C = 2 \pi r \]

Answer 5

my head hurts too much thinking

Answer 6

oh sorry

Answer 7

what is the radius?

Answer 8

Answer 9

Remember \(\large Radius = \frac{1}{2}Diameter\)

Answer 10

so 2 x 3.14 x 2?

Answer 11

But remember the equation?

\[\large C = 2\pi r\]

we can also write that as

\[\large C = \pi d\]

right? *2r = d*

So you were right on the money before...12 times 3.14 = ?

Answer 12

37.68

Answer 13

:D okay, thanks!

Answer 14

Right :)
