Question

how do i find the arc of a circle of radius 81cm intercepted by the central angle of a=2radians???

Answer 1

please help

Answer 2

what's the circumference of this circle

Answer 3

not given

Answer 4

can you find the circumference of this circle

Answer 5

2 pie r

Answer 6

r is what

Answer 7

81

Answer 8

so it's 2*pi*81 = ???

Answer 9

calculater says error?

Answer 10

replace pi with 3.14

Answer 11

ok so 508.68

Answer 12

arc / circumfrence = angle / 2 pie?>

Answer 13

now compute

2/(2pi) = 2/(2*3.13) = ???

Answer 14

i mean

2/(2pi) = 2/(2*3.14) = ???

Answer 15

???? those aret he same is that all it is

Answer 16

what is 2/(2*3.14)

Answer 17

0.318

Answer 18

that's the number you multiply with the with circumference to get your answer

Answer 19

0.318*(Circumference) = ???

Answer 20

161.76

Answer 21

so redius = pie * circumfrence>?

Answer 22

or 2 pie?

Answer 23

circum is 2pie r and r=2 pie ?

Answer 24

not sure what you're saying

Answer 25

2/(2pi) = 2/(2*3.14) = ???

Answer 26

i got 0.318 from that.. how was that equation determined?

Answer 27

(given angle)/(number of radians in a complete circle)

Answer 28

2/ (2pie) is given angle and whats the 2 pie?

Answer 29

2pi is the number of radians in a complete circle

Answer 30

nvm gor ir thx!!
