In the expenditure pie diagram, the percentage of house rent is 15%. What is the central angle of house rent in the pie diagram?

To find the central angle of house rent in the pie diagram, we need to first calculate the total central angle of the pie diagram.

Since the percentage of house rent is 15%, the central angle of house rent can be calculated as follows:

Central angle = (15/100) * 360 degrees
Central angle = 54 degrees

Therefore, the central angle of house rent in the pie diagram is 54 degrees.

90 degrees
