The length of minute hand of a clock is 5.6 cm. What is the area covered by this in 10 minutes	Choose the correct option:
A) 15.27
B) 16.27
C) 17.27
D) 16.41
E) 19.27
area of circle is pi*r^2   but in 10 minutes area covered is  (10/60)*360= 
<gadget id="calculator"> (10/60)*360</gadget>
<output>60</output>
60 degree   so formula is pi*r^2*(angle/360)=3.14*(5.6^2)*(60/360)=16.41 cm^2   ANSWER:16.41
<result>D</result>
