The floor of a room is constructed with 200 tiles, of rhombus shaped, and the dimensions of each tile are 24 cm and 18 cm. Find the area of the floor

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)
