or:A=\u03c0r^2so to find the area in square feet of a circle 38\" in diameter, first you should convert the inches into feet (38\" becomes about 3.2 feet). as 3.2 feet as the length of the diameter, and you need the find the radius (r), simply divide it by two (that is, it becomes 1.6 feet). after that substitute the value of r into the equation, to get the area. The answer is approximately 8.04 square feet.
