2*16*3.14=100.48
Answer D
Explanation:
Circumference = 2*pi*radius
You gather the like terms together.
if you have -3y +2x +6w -4 + 3y -5x +2w
you put the like terms together
so for the term y:
you have -3y +3y = 0
for x:
2x - 5x = -2x
for w:
6w + 2w = +8w
and you also had -4. if you put them together you get
0 -2x +8w -4
which is
-2x +8w -4
hope this helps
If the radius is tripped, the volume will increase by 3^3 = 27 times.
Answer: 27 times
