Given:
V = 324 cu cm
h = 9 cm
Since the formula for the volume of a cylinder is V = AreaBase*height
AreaBase = V/height = 324cu cm/ 9 cm
AreaBase = 113.04 square centimetres
Therefore, the area of the pillar in square centimeters is 113.04.

Answer:
First one
Step-by-step explanation:
The first one
y = 6.6 (1/2 ) ^n where n = the number of half lives
42 days/ 14 days/halflife = 3 halflives
X=60degrees
bc you find 180-125 bc it is a straight angle. You get 55 degrees. Then you add 65+55=120. 180-120=60 degrees. This is because every triangle must have a sum of angles that equals 180 degrees.
Hope this helps.
Changing 
"inverts" the orientation of the x axis, so the graph of f(x) is transformed by reflecting it about the y axis.
The answer is A.
The population doubles every year, so that means we multiply the original population of 150 by 2 each year.
