13 cm is the required answer
Step-by-step explanation:
According to the Question
It is given that
→ Radius of base ,b = 12cm
→ Height of cone ,p = 5cm
We have to calculate the slant height of the cone .
Let the slant height of cone be h cm
Using Pythagoras Theorem
h² = b²+p²
Where,
h denote slant height
b denote Base
p denote Perpendicular height
Substitute the value we get
→ h² = 12² + 5²
→ h² = 144 + 25
→ h² = 169
→ h = √169
→ h = 13
Hence, the slant height of the cone is 13 cm.
