Barrett purchased a piece of sandpaper for his electric sander, as shown above. The radius of the sandpaper is 4 inches.
Approximately what area does the sandpaper cover ignoring the center hole? (Use 3.14 for .)
Since the sandpaper is in the shape of a circle, we can calculate the area using the formula for the area of a circle:
Area = π * radius^2
Plugging in the radius of 4 inches, we get:
Area = 3.14 * 4^2
Area = 3.14 * 16
Area = 50.24 square inches
So, the sandpaper covers approximately 50.24 square inches of area ignoring the center hole.
