### Question

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

### Explanation:

$$\frac{r}{h}$$ = tan yo
h = $$\frac{r}{tan y^o}$$
= r cot yo

## Dicussion (1)

• $$\frac{r}{h}$$ = tan yo
h = $$\frac{r}{tan y^o}$$
= r cot yo
