Quadrilateral ABDE is a rectangle. AB = 10 cm and AE = 16 cm.

Rectangle A B D E is shown. Point C is the midpoint of side D B, point G is the midpoint of side B A, point F is the midpoint of side E A, and point H is the midpoint of side D E. Side A E is 16 centimeters and side A B is 10 centimeters.

Through which two points could a line of rotation be placed so that the base of the resulting cylinder will have a radius of 5 cm?

D and E
B and D
C and F
G and H

G and H.

Reason: G(5,0) and H(5,16) lie on the vertical midline x = 5, which is 5 cm from each vertical side (x = 0 and x = 10). Rotating about GH gives a cylinder whose radius = 5 cm.
