Question

The volume of a cone with base radius 7cm is 462 cu . find its height

Answer 1

Step-by-step explanation:

volume of cone = πr²h/3

462=22/7*7*7*h/3

462*3/22*7=h

21*3/7=h

63/7=h

9cm=height of the cone.

Answer 2

Answer:

height =9cm

Step-by-step explanation:

Given :r=7cm

volume of a cone =462 cu cm

Volume of a cone=1/3×22/7×r2×h

462×3=22/7×7×7×h

462×3/22×7=h

By solving

we get 9cm=height
