Question

if the height of a cone is tripled and radius is doubled, then its volume will become ..........times​

Answer 1

Answer:

the height of the cone is tripled then the radius becomes double the volume becomes three times

Answer 2

Answer:

6

Step-by-step explanation:

volume of cone = 1/3πr^2h

if height is tripled and radius is doubled then the volume of cone be

$\frac{1}{3} \pi(2 {r}^{2})(3h)$

but the volume of cone is

$\frac{1}{3} \pi {r}^{2}$

then the volume of cone be

$2 \times 3( \frac{1}{3} \pi {r}^{2} )$

$6( \frac{1}{3} \pi {r}^{2} )$

hence the volume will be six times
