Answer:
Vertical angle of the right circular cone = 60 degree
radius of the cone (r) = 15 cm
In the triangle ABC ∠ABC = 30°
BC = 15 cm
Opposite side (BC) = 15 cm
Adjacent side (AB) = ?
Hypotenuse side (AC) = ?
from here we need to find the measurement of the side AC. So we have to use Sinθ.
Sin θ = Opposite side/Hypotenuse side
Sin 30° = BC/AC
(1/2) = 15/AC
AC = 30 cm
Slant height (L) = 30 cm
