Question

(Confused!!!!!) What is the arc measure of a sector with area 38.485 ft2 and radius 7?

Answer 1

Answer:

arc measure(m) = 90

Step-by-step explanation:

Area = arc measure/ 360 x(times) π (r)2

38.485 = m/360 x  π(7)^2  

38.485 = m/360 x 49π

49π = 153.94

m/360 x  153.94=38.485

153.94/360 m =38.485  

360/153.94 x 153.94/360 m =360/153.94 x 38.485  

2.34 x .43m = 2.34 x 38.485  

1m = 90

Answer 2

Area of circle= 153.93804

(38.485/153.93804)*360=90.00114592

so about 90 degrees or 10.99557429

Hope this helps and feel free to leave a rate, thanks and brainliest (it would really help me get to virtuoso I would appreciate it a lot) ;)
