E and C are correct. Although E is the simplified answer
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>

20%= 0.2
0.2(360)=72
360+72=432
432-50=382
An isosceles triangle has two equal sides.
a= one equal side
b=base
b+2a=35
a=b+4
b+ 2(b+4)=35
b+2b+8=35
3b+8=35
3b=27
b=9
a=13
