A real life application problem involving the conic : circle ?

Question

Include an explanation (answer)

Answer 1

A merry-go round, or carousel, or other similar circular carnival ride.

You could use the formula for a circle:

x² + y² = r²

Where r is the radius of the merry go round. For example, if the radius was 5 metres, r = 5. So:

x² + y² = 5²
