It seems like you want to calculate the induced emf in a rotating coil. Here are the steps to do that:

1. First, we need to calculate the area of the coil. The formula for the area of a circle is πr². The radius is half the diameter, so in this case, it's 0.15/2 = 0.075 m. So, the area is π*(0.075 m)² = 0.0177 m².

2. The magnetic flux through the coil is given by the formula Φ = B*A*cos(θ), where B is the magnetic field strength, A is the area, and θ is the angle between the magnetic field lines and the normal (perpendicular) to the coil. Since the coil is rotating, the angle θ changes with time, and we can write θ = ωt, where ω is the angular velocity and t is time.

3. The rate of change of the magnetic flux is then dΦ/dt = B*A*-sin(θ)*dθ/dt = -B*A*ω*sin(ωt).

4. According to Faraday's law of electromagnetic induction, the induced emf is given by the negative rate of change of the magnetic flux, i.e., emf = -dΦ/dt. So, the magnitude of the induced emf is |emf| = B*A*ω*sin(ωt).

5. However, we don't
