## gabbyalicorn one year ago 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.

I'm thinking 37.68. $3.14$

2. gabbyalicorn

3.14 x 12

C = 2pir? $C = 2 \pi r$

5. UsukiDoll

my head hurts too much thinking

Remember $$\large Radius = \frac{1}{2}Diameter$$

10. gabbyalicorn

so 2 x 3.14 x 2?

11. johnweldon1993

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 = ?

37.68

:D okay, thanks!

Right :)
