I need help :(

OpenStudy (anonymous):

radian = angle x pi / 180 Then radian = arc/radius

OpenStudy (anonymous):

whats arc ? I got 1/9 = 188.4

OpenStudy (anonymous):

so ur radian = pi/4 Pi/4 = arc / radius So arc = pi*radius/4 =pi*30/4 =15 pi/2

OpenStudy (anonymous):

thats your answer

OpenStudy (anonymous):

you want me to solve it ? or your saying 15 pi/2 is the answer

OpenStudy (anonymous):

because when I solve it I get 23.55 ?

OpenStudy (anonymous):

15 pi/ 2 is ur arc, u wantd answer in pi ryt

OpenStudy (anonymous):

im going to send a picture hold on okay

OpenStudy (anonymous):

wel if u put pi's value whch is 3.14, u'l get 23.5 Bt u wantd answer in pi, So thats the method

OpenStudy (anonymous):
