Answer:
Volume of cone = 169.6 cubic unit
Step-by-step explanation:
In the given triangle height of the triangle is 9 unit and the base is 2 units.
Now this triangle is rotated around x-axis which forms a cone with circular base of radius = 9 unit and height of 2 units
Now volume of this cone formed will be
V = (1/3)π×r²×h
V = (1/3)(3.14)(9)²(2) = (1/3)(3.14)(162) = (3.14)(54) = 169.6 unit³
Therefore the resulting solid is a cone with a circular base of radius 9 units, height 2 units and volume 169.6 cubic unit.

Answer:
Option 1. Down 2, right pi over 3.
Step-by-step explanation:
In a given function f(x) = -7 sin(3x+π)-2 we have to find the shift horizontally and vertically.
As we know in a sine equation represented as y = a sin(bx+c) +d
Amplitude of the wave = a
Period =
Horizontal shift =
Vertical shift = d
From the given sine function we can get the following values
a = 7
period =
horizontal shift = in the right side since it's with positive sign.
Vertical shift = -2 down with 2 ( since it's with negative sign)
Therefore Option 1 is the correct one.
