Calculate area enclosed by a circle of diameter $$1.06\ m$$ to correct number of significant figures.


ANSWER

 $$ 0.883 m^2$$


SOLUTION
Area = $$ \pi (\dfrac{d}{2})^2  $$
$$ \Rightarrow Area = \dfrac{22}{7}\times 0.53^2 = 0.882828 $$
But, no of significant in diameter should be equal to the no. of significant in Area, so Ans is $$ 0.883 m^2$$
