A right circular cone has a volume of 30π m. If the height of the cone is multiplied by 6 but the radius remains fixed, which ex
pression represents the resulting volume of the larger cone?
1 answer:
Volume (cone) = (1/3)πr²h, at the same time Volume (cone)=30π
(1/3)πr²h=30π,
If the height is multiplied by 6, we will need to multiplied by 6 both sides of the equation (1/3)πr²h=30π.
(1/3)πr²*(6*h)=6*30π
So the volume of the new cone is going to be
Volume (new cone)=6*30π =180π

Do cross multiplication
<u>6</u> = <u>x</u>
18 12
Now cross multiply
(6)(12) = (18)(x)
72 = 18x
Divide both sides by 18
<u>72</u> = <u>18x</u>
18 18
4 = x
