    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
