To solve this, you must first find the area of the whole clock. As you know, the area of a circle is found by the equation

Area = pi*(r^2)

In this equation, r stands for the radius of the circle.

We will assume that the minute hand is the radius. So then our equation is

Area = 3.14*(49) because 49 is 7 times 7.

So the area of the whole circle is 153.86 cm^2

The area traced by the hand in the time you mention is one-third of the total area. That is because there are 12 intervals on a clock face (5 minutes each). The time you mention covers 4 intervals. Therefore, the area traced is

51.29 cm^2
