Challenge
A Ferris wheel has radius 25 m and its centre is 30 m above the ground. A seat starts at the 3 o'clock position and the wheel turns counterclockwise.
Find h, the height in metres of the seat above the ground after 210°. Write h = ... with the numbers in, then a line with h worked out exactly. Then press Check.
