2. Find the distance between point A and point B. 5 units
6 units
7 units
8 units

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
