Question

The circumference of a circular patio with a radius of 3 feet, 3 inches is ____.

Answer 1

Convert to all inches or all feet and then use circumference equals two * pi * radius.

Answer 2

It's 39 inches total.

Answer 3

Pie is 3.14 right?

Answer 4

That is an approximation for it

Answer 5

Most calculators have a built in pi button also

Answer 6

I got 244.92. When I posted this question yesterday I was told the answer was 20 feet, 5 inches and that's not correct.

Answer 7

That is if you convert

Answer 8

How do I convert it?

Answer 9

245 inches is 20 feet 5 inches

Answer 10

you would take the answer and first divide by 12 to get the feet part.

Answer 11

So the answer is correct? I'll have to ask my teacher tomorrow to make sure.

Answer 12

Yes that is the same answer just not converted into feet and inches

Answer 13

Anyways you would divide by 12 which gives you 20 and a fraction

Answer 14

if you then take the fraction and multiply by 12 you will get the left over inches.

Answer 15

I got 20.41 after dividing it.

Answer 16

Didn't we do this question together yesterday?

Answer 17

We did but I went to class today and was told the answer isn't correct.

Answer 18

I'm really finna just give up and let the teacher explain it.

Answer 19

.41*12 is approx 5

Answer 20

20.41

20 feets + 0.41 feet

5/12 inches is 0.41 feet

20.41 = 20 feet 5 inches

Answer 21

(5 inches is appoximately 0.41 feet)

Answer 22

Ask your teacher what format the answer should be written in :-)

Answer 24

Ok I will. 👍

Pie is 3.14 right?
To demonstrate the depth of your understanding of basic math, please use the spelling pi, not pie. I like cherry pie, but leave that aside when discussing circles. pi, OK?

Answer 26

"The circumference of a circular patio with a radius of 3 feet, 3 inches is ____ ??? "


Note: 3 ft, 3 in, is the same as 3.25 ft, or 3 1/4 ft. Prove this.

Circumference: 2 pi r (2 times pi times the length of the radius, r).

Answer 27

Thus, Circumference, C, is \[C = 2 \pi (3.25 ft) \]

Use a reasonable approx for pi, such as 3.14, as you have no justification for using more decimal places than that.
