Question

a ferris wheel is 42ft in diameter, how many feet does a passenger travel in one full turn

Answer 1

Since, it is one full turn, this impilies the angle is 360°

θ = 360 x π/180 = 2π

S = rθ

But diameter is given to be 42 ft

r= d/2 = 42/2 = 21

S = 21 x 2π

= 42π

=131.95 ft

The distance the passenger travelled is 131.95 ft
