Acone-shaped hole is drilled into a solid cube of metal as shown. if the cube has sides of length 7 cm, what is the volume of the metal after the hole is drilled? let π ≈ 3.14 and round your answer to the nearest tenth.

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

my computer is slow i can not see it sorry
