Which revolution will generate this hemisphere? Rotate a semicircle 180° about its diameter.
Rotate a circle 180° about a diameter.
Rotate a trapezoid 180° about one of its bases.
None of the other answers are correct
Rotate a rectangle 180° about one of its sides

Rotate a semicircle 180° about its diameter

Step-by-step explanation:

For common figures, the shape of a figure that revolves about a line which is at the base of the figure to give a 3 dimensional shape is the shape of the cross section of the 3 dimensional figure when the angle of revolution is 180° and half the shape of the cross section of the formed 3 dimensional figure, when the angle of revolution is 360°

The cross section of an hemisphere is a semicircle, therefore, the shape of an hemisphere is formed by rotating a semicircle 180° about the diameter (which is the straight line at the "base") of the semicircle

Therefore;

The correct option that gives the revolution that will generate the hemisphere is;

Rotate a semicircle 180° about its diameter.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
