A cone is 8cm high and its vertical angle is 62 degrees find the diameter of its base
After you make a diagram of the cross-section you should see that
tan32° = r/8
r = 8tan31° = 4.807
so if the radius is appr 4.807 , the diameter is .....
tan32° = r/8
r = 8tan31° = 4.807
so if the radius is appr 4.807 , the diameter is .....
