When recording live performances, sound engineers often use a microphone with a cardioid pickup pattern because it suppresses noise from the audience. Suppose the microphone is placed 2 m from the front of the stage (as in the figure) and the boundary of the optimal pickup region is given by the cardioid r = 4 + 4 sin(8), where r is measured in meters and the microphone is at the pole. The musicians want to know the area they will have on stage within the optimal pickup range of the microphone. Answer their question. (Round your answer to two decimal places.) 43.47 stage audience. m² 6 m 2 m microphone

I need help with this problem and an explanation of the solution described below (This is based upon Polar Curves):
Transcribed Image Text:When recording live performances, sound engineers often use a microphone with a cardioid pickup pattern because it suppresses noise from the audience. Suppose the microphone is placed 2 m from the front of the stage (as in the
figure) and the boundary of the optimal pickup region is given by the cardioid r = 4 + 4 sin(0), where r is measured in meters and the microphone is at the pole.
The musicians want to know the area they will have on stage within the optimal pickup range of the microphone. Answer their question. (Round your answer to two decimal places.)
