Answer:
vol of cylinder = per. of base x height + 2 (area of base)
area of base = pi x r^2
4pi = pi r^2
4=r^2
r=2
per of base = 2 x pi x r
2xpix2=4pi (same as area cause 2x2 and 2^2 is the same thing)
4pi + 2(4pi)
4pi + 8pi
<u>12pi = volume</u>

Answer:
C) 63
Step-by-step explanation:
3 cakes translates to 30 minutes each, so 1.5 hours. If he worked 12 hours total and 1.5 were used to make cakes then the rest were used for cupcakes. This means 12-1.5 = 10.5 hours were spent on cupcakes.
Each cupcake takes 10 minutes, which means in 10.5 hours, or 630 minutes, 63 cupcakes can be made. So C
The point P(–4, 4) that is of the way from A to B on the directed line segment AB.
Solution:
The points of the line segment are A(–8, –2) and B(6, 19).
P is the point that bisect the line segment in .
So, m = 2 and n = 5.
By section formula:
P(x, y) = (–4, 4)
Hence the point P(–4, 4) that is of the way from A to B on the directed line segment AB.
Slope is cost per arrangement so 3+10d
0 arrangements cost 0 dollars so there is no y-intercept.
Thus we get C=(3+10d)x where x is the number of arrangements
