My teacher says the answer to this math question is 88 but I think she's wrong

A lawn sprinkler sprays a circular pattern 14 feet out from the sprinkler head. About how many square feet of lawn does the sprinkler water?

At your kid's age, I hated math, too. Not any more!

Lol, yep she's wrong. Probably thinking circumference. Area is pi times the radius squared.

And the radius is 14.  14 squared would be 196.  196 times pie would be 615.44.  Is this right?
