Question
**Problem 2: Surface Area of a Paraboloid Inside a Cylinder** Find the surface area of the part of the paraboloid defined by the equation \( z = x^2 + y^2 \) that lies inside the cylinder given by \( x^2 + y^2 = a^2 \). **Explanation:** - **Paraboloid**: The surface described by the equation \( z = x^2 + y^2 \) is a paraboloid. This is a three-dimensional shape where the cross-sections parallel to the \(xy\)-plane are circles, and those parallel to the \(xz\) or \(yz\) planes are parabolas. - **Cylinder**: The equation \( x^2 + y^2 = a^2 \) describes a cylinder with its axis along the \(z\)-axis and a radius of \(a\). The task is to compute the surface area of the portion of the paraboloid that is contained within the given cylinder.
