Answer:
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.
7x13=91 meaning 13 pies were made in total. Since the cafeteria contributed 3 we can subtract 3 from 13. Ultimately meaning that the club contributed 10 pies.
The answer is 10.
