CHA-5.D—Calculate areas of regions defined by polar curves using definite integrals question 1

[Maximum number: 2]

Let S be the region bounded by the graph of the polar curve r(θ)=3θsin(θ2)r(\theta)=3 \sqrt{\theta} \sin \left(\theta^{2}\right) for 0θπ0 \leq \theta \leq \sqrt{\pi}, as shown in the figure above.

Find the area of S.
