Question

x/360*pi*3^2=

Answer 1

I would help you but this doesn't make sense... Are you sure you have it written correctly?

Answer 2

i believe so.. i cant draw the circle

Answer 3

Is there an x on the circle somewhere?

Answer 4

I take it that the radius of the circle you are speaking of is 3

Answer 5

ya

Answer 6

I am guessing there is an angle on your circle. Do you know what the degree of the angle is?

Answer 7

there is an angle but it doenst show the measurement

Answer 8

Maybe you are supposed to measure it with a protractor? I believe you are trying to find the area of that circle... it must have a shaded area or something.. Does it tell you what the area is anywhere on the problem?

Answer 9

do you have a yahoo or something i could send the picture to becuase it is hard to explain

Answer 10

send it to amcbeth@wacohs.com

Answer 11

okay

Answer 12

ok i got it sent.. theres three that i need help on

Answer 13

I haven't gotten yet.. When I do.. I will let you know

Answer 14

Sometimes that email account filters things out... can you send it to amcbeth328@gmail.com that one will work quicker.

Answer 15

ok

Answer 16

OK I got them... I can't really read it... but it looks like there is stuff written on the right side of the pictures. I am not sure you actually do the first problem. What it is telling you is to find the area of part of a circle you do the following.

The area of a whole circle is A = pi r^2. So in the first problem, you are trying to find out the area of part of a circle... If you were trying to find out what half of a circle was you would take A = 1/2 pi r^2. But you aren't finding 1/2 of the circle you are finding a part of the circle. Since circles are measured in degrees you are finding a portion of the 360 degrees. that is the x/360 if you put in 180 degrees for x you would have 180/360 which is 1/2 of a circle which is exactly what 180 degree angle would look like when you color the top part of that circle.

So .... I think the answer to the first one is what you wrote down on the problem x/360 * pi * 3^2 because we don't know the degree of the angle but the radius is 3.

In the next two problems... it tells you the degrees and the radius. I can't read them. but put (degree of the angle)/360 * pi * radius^2. They tell you the radius also so you plug that in. If you want to tell me the numbers I can help you out.

Answer 17

okay the second one is the degree is 52 and the radius is 17ft
the last one is 160 degrees and radius is 5m

Answer 18

So you put 52/360 * pi * 17^2 put that in a calculator and you will get your answer.

You would put 160/360 * pi * 5^2...

Answer 19

so for this one 52/360 * pi * 17^2 i got 131.08
and this one 160/360 * pi * 5^2 i got 34.89

Answer 20

Make sure you right is with like inches^2 or cm^2 what ever the radius is in. Yes those are the answers... could be a little different depending if you used the pi key or you use 3.14. Good answers tho.. just label them

Answer 21

thank you
