Circumference = 2πr
r = 9
Circumference = 2π(9)
Circumference = 18π
Circumference = 18(3.14)
Circumference = 56.52
Distance: 56.52 meters
To find the area, your just supposed to multiply
The correct answer is B, because 65+0.20x140=93. You must multiply 0.20 times 140 first, and get 28 and than add 28+65=93.
