Question

I Just Need The Answer.

Amanda's family has a swimming pool that is 4 feet deep in their backyard. If the diameter is nearly 25 feet, what is the circumference of the pool?

Express your answer to the nearest whole foot.

Answer 1

what is the formula for circumfrence?

Answer 2

25*pi

Answer 3

if swimming pool is circular

Answer 4

so that would be the answer?

Answer 5

3.14*25

Answer 6

78.5?

Answer 7

is that the answer?

Answer 8

Yes that is the answer.

Answer 9

thank you

Answer 10

is it to the nearest foot if it is 78.5?

Answer 11

Nearest foot would be 79 ft

Answer 12

no, so let's assume that "nearly" 25 feet means it is close to, but actually a little less than 25 feet.

Answer 13

alternatively, if you use a more accurate version of Pi and stick with 25 feet then Natalie is technically correct.

Answer 14

25*3.14=78.5= 79 ft

Answer 15

yes, 3.14 * 25 is 78.5
Now, since the question asks you to give an answer to the nearest foot you need to decide:

if Pi = 3.14 then what tie breaker will you use to determine how to round 78.5. There are many alternatives

if Pi =3.141592 then the answer is slightly more than 78.5 and we would round up.

If "nearly 25 feet across" means something slightly than 25 then the answer would be slightly less than 78.5 and we would round down.

so, you need to pick a set of assumptions to conclude for yourself if the final answer is 78 or 79.

In my opinion both answers are valid and the question is poorly worded.
