What happens to the volume of a cone when the height is doubled ?

Answer-

When the height is doubled, the volume of the cone also gets doubled.

Solution-

Volume of a cone is given by,

Where,

V = Volume,

r = radius of the base,

h = height of the cone.

Let, height at first be x, then volume would be,

As the height is doubled, so height = 2x, then volume would be,

Therefore, when the height is doubled, the volume of the cone also gets doubled.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
