Question

Bill measures the circumference of a circular fish pond to be 28 ft.



What is the diameter of the fish pond, rounded to the nearest foot?

Use 3.14 to approximate pi.

So, 3.14 x 28 x 2 / 2 ? am i right on how i am doing this?

Answer 1

You already know the circumference. There should be some division in there in order to find the diameter or the radius.

Answer 2

yes, after i get the answer which would be 175.84 then i would divide it by 2 which would be 87.92

Answer 3

Answer 4

am i right?

Answer 5

hint:
If C is the measure of the circumference, and D is the measure of the diameter, then we can write this:
\[\Large C = 3.14 \times D\]
so we have:
\[\Large D = \frac{C}{{3.14}} = \frac{{28}}{{3.14}} = ...feet\]

Answer 6

You didn't listen. Why would the diameter be greater than the circumference.

Circumference = 2 * Radius * pi

Circumference = Diameter * pi

Rethink!

Answer 7

brb for a sec

Answer 8

okay, back

Answer 9

3.14 / 28 ?

Answer 10

no, please look at formulas of @tkhunny, or at my formulas above

Answer 11

i did

Answer 12

we have:
\[\Large D = \frac{C}{{3.14}} = \frac{{28}}{{3.14}} = ...feet\]

Answer 13

yes,
