Answer 2

Answer:

Area of clock covered = 183.16$cm^{2}$

Step-by-step explanation:

Let us assume that the clock is in circle shape.

∴ Let the radius of the circle=length of minute hand

                                              =10cm

Hence the area covered by the minute hand=area of sector

Here,∅=210°

Area of sector= $\frac{\pi r^{2} }{360}$×∅

                       = $\frac{\pi 10^{2}*210}{360}$

                       = $\frac{314*100*210}{100*360}$

                       = $\frac{314*7}{12}$

                       = $\frac{157*7}{6}$

                       = $\frac{1099}{6}$

                       = $\frac{18316}{100}$

                       = $183.16$$cm^{2}$
