The immersion angle of the drum in a rotary vacuum filter is 120°; how can the immersion area be determined?

Question 21 from the 2016 morning session of the registered chemical engineering professional exam: \"A suspension is filtered using a rotary vacuum filter under a constant pressure difference. The immersion angle of the drum is 120°; the filter cake is incompressible, and medium resistance can be ignored. What is the percentage increase in its production capacity when the drum’s immersion angle is increased to 150°, while the filtration time remains unchanged? Choose the correct option.\" ” (A) 11.8 (B) 12.5 (C) 25 (D) 56.3 How is this calculated? No formula for calculating the immersion area based on the drum immersion angle was found.
Is it usually calculated using which formula?
The angle divided by 360 gives the immersion rate
