To find the average add all the scores together, then divide that by the number of quizzes.
77 + 71 + 82 + 79 + 76 + 78 + 85 + 83 = 631
8 quizzes
Average = 631 / 8 = 78.875 = 79

Answer:63
Step-by-step explanation:
Length of arc =14π
Φ=80°
Radius =r
Length of arc =Φ/360 x 2 x π x r
14π=80/360 x 2 x π x r
14π=(80x2xπxr)/360
14π=160πr/360
Cross multiply
14π x 360=160πr
5040π=160πr
Divide both sides by 160π
5040π/160π=160πr/160π
31.5=r
Diameter =2 x r
Diameter =2 x 31.5
Diameter =63
