The area of a circle is: pi times radius squared
There are two ways to answer your question. If you mean the circle is 16 feet wide (diameter), then the square footage is 201.06 square feet. However, if you mean the circle is 16 feet around (circumference), the square footage will be 20.372 square feet.
If that's its diameter then: pi*60^2 = 3600*pi square feet
To find the square footage multiply both the length and width of the room. So for 72 feet wide and 156 feet long room the square footage is = 72 feet X 156 feet = 11232 square feet.
1400 square feet
225 square feet
26 * 9 = 234 square feet
200.96 ft squared
540
To calculate the square footage of a room, you multiply its length by its width. For a room that is 21 feet long and 14 feet wide, the square footage would be 21 x 14 = 294 square feet.
It is 62 times 24 = 1488 square feet
13 * 13 = 169 square feet.
330 square feet
