Question

The volume of a cone is 1570 cmcube.if its base area is 314cmsquare, then its height is​

Answer 1

given :-

base area of the cone = 314cm²

we know that the base of a cone is circular.

so we can write as,

=> πr² = 314cm² …(i)

now, the volume of the cone us given = 1570cm³

formula for the volume of a cone is 1/3πr²h

therefore 1/3πr²h = 1570cm³ …(ii)

putting value of (i) in (ii)

=> 1/3 × 314 × h = 1570cm³

=> h = (1570 × 3)/314

=> h = 5 × 3

=> h = 15cm

hence, the height of the cone is 15cm.
