Suppose i want to do a new survey of us adults to estimate the proportion of us adults that currently belong to the gym. i want to estimate the proportion within a margin of error of 0.02 at a confidence level of 99%. a previous survey found that an estimated 20% of us adults belong to at least one us health club. how many us adults do i need to get responses from this new survey

the square root of what number? if you add that, then someone will probably answer the question.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
