what is the area of the circle, in square inches, created in a hand sweep in an hour

solve the area of the whole circle since in an hour, the minute hand covers the whole clock assuming that the minute hand reaches all the way out to the edge of the clock the minute hand is the radius area=pi times r^2 r=5 5^2=25 area=pi times 25 area=25pi aprox pi=3.14 25 times 2.14=78.5 area=78.5 in^2
