The answer would be 79 r 1
Hope this helps! :)
Answer:
the correct answer would be option 4, since both triangle ACD and triangle ECB
Answer: the real question is, where is the second fraction?
To find the length of the arc, we will use the formula,
arc length = 2πR (C/360)
where,
R is the radius of the arc, which is 8"C is the central angle, which is 45°
pi is approximately equivalent to 3.14
Applying the formula,arc length = 2πR (C/360)
arc length = 2(3.14)R (45°/360)
arc length = (6.28)(8") x (0.125)
arc length = (50.24") (0.125)
arc length = 6.28"
The length of the arc is 6.28". 6.28 is also equivalent to 2π, hence, the answer is 2π.
