Volume = 1/3 * pi * r^2*h
= 1/3 + pi * 4*2 * 6
= 8pi m^3
If you know the slope and a point, the best option is to represent the line in the point-slope form which is:
(y-y1)=m(x-x1), where (x1,y1) is the point and m=slope
1000000+1/10. There are no rules for when you add the powers.

There are 2 answers: choice C, choice D</h3>
====================================================
Explanation:
32% = 32/100 = 0.32
32% of 400 = 0.32*400 = 400(0.32), which adds onto the original 400 to get 400+400(0.32). This is why choice D is one of the answers.
We can factor out the GCF 400 to go from 400+400(0.32) to 400(1+0.32) which then simplifies to 400(1.32) or just 400*1.32. This shows choice C is the other answer. Using a calculator,
400+400(0.32) = 400 + 128 = 528
400*1.32 = 528
meaning that 400+400(0.32) = 400*1.32
The other answer choices result in other values, showing that they aren't equivalent to 528.
