1.	The radius of a circle is 1.22 m. Area enclosed by it upto correct significant figures is
Answer» `4.6778 m^(2)` `4.677 m^(2)` `4.67782 m^(2)` `4.68 m^(2)` Solution :AREA =`PIR^(2)= (22)/(7) xx(1.22)^(2)= 4.67782 m^(2)` As PER rule, the area will have three significant figures. Rounding off, we get, `A=4.68 m^(2)`
