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>
Two possible numbers that might have a GCF common factor of 5 are 10 and 15, as well as 25. 5 is also the greatest common factor of itself.
So your numbers are : 5, 10, 15, and 25.
Answer:
2r+1+(-4r)+7
= -2r+8
= -2(r+4)
Step-by-step explanation:
Answer:
The novel has 2160 pages.
Step-by-step explanation:
The number of pages of the novel is x.
Mica has read 1/2 of the novel, so x/2 = 0.5x.
Denise has read 2/5 of the novel, so 2x/5 = 0.4x.
Mica has read 216 pages more than Denise
This means that:
0.5x - 0.4x = 216
0.1x = 216
x = 216/0.1
x = 2160
The novel has 2160 pages.
