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

$0.883 m^2$

##### 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 $0.883 m^2$
