You format a document in three columns of equal width. the document is 8.5 in wide. you want left and right margins of 1 inch each. between the columns, there is a gutter that is 1/8th of an inch wide. what is the width of each column?

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)

a = 11 : 4

b = 38

c = 1 for every 6

a
