The London Eye is not what you might think, a Ferris wheel. The London Eye is the world's tallest cantilevered observation. The diameter of the wheel is during one revolution of the wheel. Use 3.14 for π

1,391 feet
2,782 feet
695.5 feet
2,086.5 feet

please say the correct answer and why.

2,782 feet. This is because the diameter of the wheel is calculated by multiplying the circumference (2πr) by the radius (r). The circumference of the wheel is 2π x 695.5 feet, which equals 2,782 feet.
