Volume of cone is (1/3)π r² h.
So since diameter is 18 inches, radius is 9 inches, right?
So just plug in values and calculate;
V = (1/3)·π·9²·14
= 378π
≈ 1187.52
C = 2 pi r given r = 4
so
C = 2 pi (4)
C = 8 pi
answer
C. C = 8pi
It is given in the question that
Point N(7, 4) is translated 5 units up.
And we have to find the coordinates of its image after this transformation.
Since the point translated up by 5 units, so the x coordinate remains same and we have to add 5 to y coordinate.
So the new coordinate after the transformation is

And that's the required coordinate after the given transformation .
Answer:
the first one is 13 and the second is 22
