. a playground is shaped like a rectangle with a width 5 times its length (l). what is a simplified expression for the distance between opposite corners of the playground?

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)

inequality:

620-37.4p ≥ 450

the minimum amount of packages needed to be removed from the elevator is 5.
