Question

Need help with number 11, Please!

Answer 1

what is 7 m supposed to be, the radius? i can't really see it

Answer 2

yes, its the radius, and both angles are equal

Answer 3

\[mEFG=\theta * \frac{\pi}{180}*r=160*\frac{\pi}{180}*7\]

Answer 4

14pi circumference, arc length as ratio of theta to total circumference
(160/360)*14pi

Answer 5

ratio of theta to total angle of circle*

Answer 6

how do i do 12

Answer 7

mEHG=14pi-mEFG

Answer 8

oops

Answer 9

hehe

Answer 10

that was surely wrong

Answer 11

14pi=43.9 which rounds off to 44 right?

Answer 12

Don't round the answers unless it says to

Answer 13

For mEFG, write it as \[mEFG=\frac{56 \pi}{9}\]

Answer 14

understand?

Answer 15

no.. im lost

Answer 16

ok the circumference is 14pi

Answer 17

C=2*pi*r=2*pi*7=14pi

Answer 18

There are 360 degrees in a circle, and the measure of angle EDG is 160º

Answer 19

so the measure of arc EFG is 160/360*14pi

Answer 20

simplifed this is 56pi/9

Answer 21

okay

Answer 22

In the unit circle (radius of 1), the measure of an arc is the measure of theta in radians

Answer 23

ok
