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.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
A B
D C
vectors
AB = DC
AB (-2-7 ; 3-1) => AB (-9 ; 2)
DC (1-x : -7-y)
1 - x = -9 => x = 10
-7-y = 2 => y = -9
D(10 ; -9)
The answer is y=-8 I’m pretty sure
