8 A circular dining room table can seat 11 people. Each person has about 2 feet of
space along the edge of the table. What is the radius of the table, rounded to the
nearest half foot?

r = 3.5 ft

Step-by-step explanation:

The circumference of a circle is the distance around the circle. The seat accommodates 11 people . Each person has 2 ft of space along the edge of the table .

Therefore ,

circumference = 11 × 2 = 22 ft

circumference = 2πr

where

r = radius

circumference = 2πr

22 = 2 × 22/7 × r

22 = 44r/7

multiply both sides by 7/44

r = 22 × 7/44

r = 7/2

r = 3.5 ft
