• V = 5πr³

• V = 5πr²

• V = 10πr³

• V = 10πr

• V = 4x³ - 90x² + 450x

• V = 2x³ - 90x² + 450x

• V = 6x³ - 90x² - 450x

• V = 4x³ + 90x² + 450x

Answer explanation

To find g(x) - h(x), we need to subtract the functions. If g(x) = 3x and h(x) = 8, then g(x) - h(x) = 3x - 8, which matches the correct answer choice.
