What solid 3D object is produced by rotating the semicircle about line m with a diameter of 5
Choose 1

(Choice A)
A
A sphere with radius 5 units

(Choice B)
B
A sphere with diameter 5 units

(Choice C)
C
A hemisphere with radius 5 units

(Choice D)
D
A hemisphere with diameter 5 units

(Choice B)

B

A sphere with diameter 5 units

Explanation:

When 2D images are rotated about a line or an axis, it always results in the formation of 3D images.

From the question above, our 2D image is the semi circle with Diameter 5 units, when it is rotated along the line m,

We would get the 3D image of sphere with a diameter of 5 units.

Therefore, Choice B is the correct option.

Please find attached to this answer the diagram that show us the rotation of the semi circle.
