Oh yay, proportional thinking! (Vicious sarcasm). Alright, let's do this:
Volume of the cylinder = <span>π(h)r^2
New volume = </span><span>π(h/3)(4r)^2
= (1/3)</span><span>π(h)(16r^2)
=16*(1/3)</span><span>π(h)r^2
=(16/3)</span><span>π(h)r^2
Therefore, it's D. Though it's spelled pi, and you should really use the ^ symbol. </span>
Hello,
f(x) = 1/9x + 2 ⇔ y = 1/9x + 2 ⇔ 1/9x = y - 2 ⇔ x = 9(y - 2)
x = 9y - 18
⇒ f⁻¹(x) = 9x - 18
