Question
The diagram above represents Edward T. Hall's concept of space surrounding a person de(med by four nonoverlapping regions. Intimate space is the region inside a circle of radius 1 foot. Personal space is the region within a circle of radius 4 feet but outside intimate space. Social space is the region within a circle of radius 12 feet but outside personal space . Public space is the region within a circle of radius 25 feet but outside social space. What is the area, in square feet, of the shaded region representing a person's social space?
- 127
- 128
- 144
- 625
The correct answer is: 128
Persons social space = Area of circle with radius 12 feet
= Area of circle with radius 4 feet
= π(12)2 = π(4)2
=144π = 16 π = 128 π
