Answer:

Option D. 51.1 cm

Step-by-step explanation:

Please see attached photo for explanation.

In the attached photo, c is the distance between the tip of the cone and its rim.

The value of c can be obtained as follow:

Angle θ = 38.5°

Adjacent = WY = 40 cm

Hypothenus = WZ = c =?

Cos θ = Adjacent / Hypothenus

Cos 38.5 = 40 / c

0.7826 = 40 / c

Cross multiply

0.7826 × c = 40

Divide both side by 0.7826

c = 40 / 0.7826

c = 51.1 cm

Thus, the distance between the tip of the cone and its rim is 51.1 cm.
