The length of minute hand of a clock is 5.5 cm. What is the area covered by this in 10 minutes Select
A) 15.27 B) 16.27 C) 17.27 D) 19.27 E) 15.83
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*(5.5^2)*(60/360)=15.83 cm^2   ANSW15.83R:15.83
