A cone and cylinder have the same height and their bases are congruent circles.
1. If the volume of the cylinder is 90 cm, what is the volume of the cone?
Plz help me!

30

Step-by-step explanation:A cone is 1/3 the volume of a cylinder.

- 1.613 = -1.6 or -1.61

-1.522 = -1.5 or -1.52

0.587 = 0.6 or 0.59

3.079 = 3.1 or 3.08

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
