Quandaries and Queries


I have a room that is 12 x 16 feet with an 8 foot diameter hole (spa) in it. How many square feet are  in this room?


Hi Stanley,

The area of the room before the hole is cut for the spa is 12 16 = 192 square feet.

The area of a circle is times the diameter where is approximately 3.14. This the area of the hole you remove for the spa is

8 = 25.13 square feet.

Hence the area remaining is

192 - 25.13 square feet or approximately 167 square feet.
