Question

Can anyone explain to me how to find the central angle of a circle?

Answer 1

if you know what a metric system i then you can get your answer through that

Answer 2

sure.. @RandiHobbs you need to compute it in a specific problem
or you want to understand the general idea ?

Answer 3

I was given a pie chart, would you like me to draw it out?

Answer 4

draw it..

Answer 5

erggg one moment, please. I drew it and it wouldn't post, let me try agian.

Answer 6

ok... press Post and wait for sometime..lol sometimes it freezes

Answer 7

ok. there is only one rule

1 Full Circle = 360 degrees

Answer 8

other 34%, Potatoes 8%, carrots 11%, Green Beans 12%, Corn 15%, Brocoli 20% In the circle graph, what is the measure of the central angle for green beans and carrots combined? Round to the nearest whole number.

Answer 9

so all grocery stuff huh :)

Answer 10

360 degrees = 100%

Answer 11

Hah, novanet is very original, isn't it?

Answer 12

so, 1 degree = \[\frac{100}{360} \]

Answer 13

green beans are 12%
carrots are 11 %
right ?

Answer 14

Yes

Answer 15

so you want to know what is the "central angle" representing 12+11 = 23 %

Answer 16

I suppose, i'm not entirely sure. That's why i asked :3

Answer 17

\[23 \times \frac{360}{100}\]

Answer 18

since 100 percent corresponds to 360 degrees, 23 percent corresponds to 23 x (360/100) degrees. can you do the arithmetic?

Answer 19

@RandiHobbs

Answer 20

No exactly =\ but can you explain it to me?

Answer 21

just multiply 23 and 360/100?

Answer 22

414/5?

Answer 23

thats right. you have calculator ?

Answer 24

you have to round the answer to nearest whole number, right ?

Answer 25

Yes and yes.

Answer 26

82.8?

Answer 27
