How does the volume of a cylinder change if the radius is quadrupled and the height is reduced to a third of its original size?
2 answers:
Oh yay, proportional thinking! (Vicious sarcasm). Alright, let's do this: <span>Volume of the cylinder = </span><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>

Answer:
743.25m^2
Step-by-step explanation:
Area of triangle = 1/2bh
= 1/2 x 30 x 26
= 390
Area of semi circle = 1/2 πr^2
= 1/ 2 x 3.14 x 15 x15
=353.25m^2
= 390 + 353.25
= 743.25m^2
