The table shows several characteristics of two United States coins. US coins are roughly in the shape of cylinders. Therefore, the formula for the volume of a cylinder can be used to compare the volumes of coins. How does the combined volume of 3 pennies compare to the volume of 1 presidential dollar? Select from the drop-down menus to correctly complete the sentence.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75

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
