Which sequence is not equivalent to the others?
a.
a reflection across the y-axis, followed by a reflection across the x-axis, and then a 90° clockwise rotation about the origin
b.
a 90° clockwise rotation about the origin and then a 180° rotation about the origin
c.
a reflection across the x-axis, followed by a 90° counterclockwise rotation about the origin, and then a reflection across the x-axis
d.
a 90° counterclockwise rotation about the origin

C. a reflection across the x-axis, followed by a 90° counterclockwise rotation about the origin, and then a reflection across the x-axis

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

the equivalent expression are always the hardest ones but you look at the gcf also
