The minute hand of a clock is 5 inches long. 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
