Answer 2

Answer:

28cm

Step-by-step explanation:

Given: Diameter of the base of a cone is 42 cm.

Volume of the cone is 12936 cm3.

Volume of the cone is given by:

× π × r2 × h

∴1/3

× π × r2 × h = 12936

⇒

× π × (

)2 × h = 12936 (here diameter = 42cm, ∴ r =

= 21)

⇒

× π × (21)2 × h = 12936

⇒ h =12936*3/π*21*21

= 28cm

∴ Height of the given cone is 28cm
