## Question

Calculate \(\iint_R (x^2 + y^2) \, dA \) for the closed bounded region \(R\) bounded above by \(y = 1 + \sin(x)\) and below by \(y = x^2\) (see the figure below). Use NIntegrate if necessary.

![Graph]
The graph displays two functions:
1. \( y = 1 + \sin(x) \) which is an oscillating curve (in orange) with a sine wave superimposed over a constant value of 1.
2. \( y = x^2 \) which is a parabola (in blue) opening upwards.

These curves intersect within the interval roughly between \( -1.5 \) and \( 1.5 \). The transition forms a closed bounded region \(R\).
