Trigonometry Quiz
Make sure to try these on a piece of paper first
In the following diagram, a circle has radius r (metres), and angle $latex \theta$ (radians), and centre O.
The area of the shaded sector is $latex \frac{6\pi }{5}$, and the length of the sector AB is $latex \frac{3\pi }{5}$.
a) Find the value of r.
b) Find the value of $latex \theta $.
In a triangle PQR, side $latex PQ=3 \; cm$, and side $latex PR=2 \; cm$. The area of the triangle PQR is $latex 2\; cm^{2}$.
