A cone is 8cm high and its vertical angle is 62 deg. find the diameter of its base

Answer»

ANSWER:

The answer is approximately around 26cm.

Step-by-step explanation:

Height of the cone =8cm.

Vertical ANGLE =62°

Then angle on each side of the height I=62°/2=31°.

Let the DIAMETER of the base be 2r.

Tan theta =Height / base=>tan31°=8/r=>0.6=8/r

=>8/0.6=r=>13.2~13.

Then d=2r=2×13=26cm approximately.
