The outside radius of a truck tire is 11 inches. approximately how far will the truck have traveled after 3 rotations of the these tires

The distance = 207.3 inches

Step-by-step explanation:

∵ The distance = number of revolution × circumference

∵ The radius of the circle = 11 inches

∴ The circumference = 2 × π × r = 2 × π × 11 = 22π inches

∵ Number of revolution = 3

∴ The distance = 3 × 22π = 66π = 207.3 inches

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.
