Question

A metallic solid cone is melted to form a solid cylinder of equal radius. If the height of the cylinder is 6 cm,
then what is the height of the cone.​

Answer 1

Answer:

Step-by-step explanation:

Volume of cone = Volume of cylinder

31​πr12​h1​=πr22​h2​

⇒31​×r2×h1​=r2×7[r1​=r2​=r]

                 ⇒h1​=7×3=21cm

Therefore, height of cone is 21 cm.
