Answer 1

well you need to know

pi = 180 degrees

so

pi/8 = 180/8

I'll let you calculate the answer...

Answer 2

and remember .5 of a degree = 30 minutes

Answer 3

so it would be the second option?

Answer 4

well its interesting... there are 2 answers the same... it depends on the accuracy needed in the question...

to the nearest minute... is option 2

to 1 decimal place or nearest 10th is option 3

Answer 5

Here's the answer and explanation to your other question:

Answer 6

well there you go..

Answer 7

Well the little quotes mean minutes and seconds. The single quotation mark ‘ means minutes. The regular double quotation mark “ means seconds. Weird I know. So its 25 degrees, 47 minutes, and 31 seconds. They call it DMS form (degrees, minutes, seconds). It's another way of writing a decimal degree measure. It's to get rid of the decimal. Here's an example:

If you wanna change 43.1025° into DMS form, first separate the parts after the decimal. Take the 0.1025 and multiply it by 60. (Kinda how 60 seconds makes a minute ya know?)

So now its 43º 6.15'

But they don't want a decimal, so take the 0.15 off of 6 and multiply 0.15 by 60 like we did to 0.1025.

Now its 43º 6' 9"
See how there's no more decimals?

Now your question is 25º 47' 31" so you have to work backwards.

Divide 31 by 60. You get 0.5167. Add this to 47.
Now its 25º 47.5167'

Divide 47.5167 by 60. You get 0.7919. Add this to 31.

Now there are no more minutes or seconds, and you have 31.7919. Round to the nearest hundredth to get 31.79.

I hope that all made sense!

Answer 8

if you post them as new questions, there are lots of people who can help...

good luck

Answer 9

Either is fine. I'll see what I can do because I'm working on my own homework too.

Answer 10

Do you have the formula for central angle and arc?

Answer 11

The formula for length of arc is S=r[theta]

So S=10*35º

But you have to convert the degrees to radians first.

35*pi/180
=35pi/180
=0.611

10*0.611 = 6.11 ft
