## Related Rates - An Oil Slick |
HELP |

The radius of a circular oil slick expands at a rate of 2 m/min. Move the point on the
slider or press the play/pause
button in the lower left hand corner to see an animation.

- How fast is the area of the oil slick increasing when the radius is `25` m?
- If the radius is `0` at time `t = 0`, how fast is the area increasing after `3` min?
