A fan-shaped garden forms a sector of a circle of radius 8 m and angle .
A circular mirror of radius is centred at . The vertices , and of an equilateral triangular frame lie on the mirror, so the three regions between the frame and the mirror are shaded. Let represent the mass of silver coating, in grams, applied to the mirror after minutes. The application rate is given by .
A circle has a radius of cm.
A sector-shaped park has radius m, where , and subtends an angle of radians at its centre in its design. Let m denote the area of this sector and m denote its total perimeter.
Solve the equation for , where is in radians.
