Question:

The height of a right circular cone is 6 cm and its base diameter is 16 cm. Find the volume of this cone.

Options:

$384π \, cm^3$

$786π \, cm^2$

$128π \, cm^2$

$512π \, cm^2$

Correct Answer:

$128π \, cm^2$

Explanation:

We know that,

The volume of a cone = \(\frac{1}{3}\)πr2h

L2 = B2 + P2

We have,

The diameter of cone = 16 cm.

The height of cone = 6 cm.

then, the Radius = = 8 cm

The volume of the cone =  = \(\frac{1}{3}\)× π × 82 × 6 = 128π cm3
