58700 because if you follow the rules of PEMDAS then you would have to exponents 10^4 is 10000 then multiply 5.87 which gives 58700
√45 = √9√5 = 3√5
√20 = √4√5 = 2√5
3√5+2√5-√5=4√5
answer = 4√5

Answer:

Step-by-step explanation:
The original questions is suppose an ant walks counterclockwise on a unit circle from the point (1,0) to the endpoint of the radius that forms an angle of 240 degrees with the positive horizontal axis.
To find the distance ant walked we find the arc length of the sector with central angle 240 degree and radius =1 (unit circle)
arc length of a sector =
arc length of a sector =
arc length of a sector =
