Answer

First find out the  what is the radius of the circle covered by the lawn sprinkler .

To prove

Formula

Where r is the radius of the circle.

As given

The spray from a spinning lawn sprinkler covers an area of 625 square feet.

Put in the formula

r = 14.11 feet (Approx)

Thus the radius of the circle covered by the lawn sprinkler is 14.11 feet.

Now find out  If Andrew is standing 30 feet away from the sprinkler will he get wet .

 As the radius of the  circle covered by the lawn sprinkler is 14.11 feet.

This means the spray from a spinning lawn sprinkler covers only 14.11 feet distance which far away from the 30 feet .

No, Andrew is standing 30 feet away from the sprinkler will not  get wet .
