Explanation Given: The function f ( x , y ) = 16 − x 2 − y 2 Formula used: Average value over a plane R is given by A v g = 1 A ∬ R f ( x , y ) d A Here, A is the area of region R. Use the integration formula ∫ x n d x = x n + 1 n + 1 Calculation: Bounds for x is given as − 2 ≤ x ≤ 2 Bounds for y is given as − 2 ≤ y ≤ 2 Plot the graph of region R from given coordinates ( 2 , 2 ) , ( − 2 , 2 ) , ( − 2 , − 2 ) and ( 2 , − 2 ) The figure of above rectangle is shown below: Area of the obtained rectangle is: ( 2 − ( − 2 ) ) ⋅ ( 2 − ( − 2 ) ) = 16 unit 2 Put the value of function, limits and area in above formula, 1 16 ∫ − 2 2 ∫ − 2 2 ( 16 − x 2 − y 2 ) d y d x = 1 16 ∫ − 2 2 [ 16 y − x 2 y − y 3 3 ] − 2
