विकल्प

• 2496 cm³

• 1248 cm³

• 1664 cm³

• 416 cm³

Answer 1

The volume of a right circular cone whose area of the base is 156 cm² and the vertical height is 8 cm, is 416 cm³.

Explanation:

Given, height of cone (h) = 8 cm

Area of base = πr² = 156 cm²

Now, volume of cone = `1/3 πr^2h`

= `1/3 xx 156 xx 8`

= 52 × 8

= 416 cm³
