A right circular cone has a base radius r cm and a vertical angle 2yo….

A right circular cone has a base radius r cm and a vertical angle 2yo. The height of the cone is
  • A.
    r tan yo cm
  • B.
    r sin yo cm
  • C.
    r cot yo cm
  • D.
    r cos yo cm
  • E.
    r cosec yo cm
Correct Answer: Option C
Explanation

(frac{r}{h}) = tan yo
h = (frac{r}{tan y^o})
= r cot yo
