    plz marks as brainliest

  • Answer : 2 cm

    Step by step explanation :

    Given :

    Radius of metallic cone = 2 cm

    Height : 8 cm

    To find : Radius of sphere

    Solution :

    Let us assume the Radius of sphere as 'R' cm.

    Here, Volume of sphere = Volume of cone.

    We know that,

    Volume of sphere = 4/3 πR³

    Volume of cone = 1/3 π r²h

    Thus,

    4/3 πR³ = 1/3 π r²h

    4/3 π R³ = 1/3 π × 2 × 2 × 8

    4/3 R³ = 1/3 × 32

    R³ = 32/4

    R³ = 8

    R = 2

    Thus, Radius of sphere = 2 cm.

    Final answer :

    Radius of sphere is 2 cm.
