The answer is 2 hopefully this helped
Area of sector = 1/2 * r^2 * x where r = radius and x = angle in radians
86 = 1/2 * r^2 * pi/4
r^2 = 2 * 86 * 4 / pi = 219
r = sqrt 219
= 14.80
Answer:
Step-by-step explanation:i havent done something like this in a long time
I got 7.64 because you round the 3 to 4 since the 7, in the 3rd decimal place is higher than 5
