a right circular cylinder, a, has radius r and height h. another right circular cylinder, b, has radius 3r and height 2h. what is the ratio of the volume of a to the volume of b ?

Respuesta :

The ratio of the volume of the rigth circular cylinder a to the volume of the right circular cylinder b is 1: 18.

According to the given question.

We have two right circular cylinder, a nd b.

Also,

The radius of right circular cylinder, a is r.

The height of the right circular cylinder, a is h.

The radius of the right circular cylinder, b is 3r.

And the height of the right circular cylinder, b is 2h.

As we know that, the volume of a cylinder can be calculated using the formula V=πr^2(h). Where r is the radius and h is the height of the cylinder.

So, the volume of the right circular cylinder a  = πr^2h

And, the volume of the right circular cylinder b = π(3r)^2(2h) = 18hr^2π

Therefore,

The ratio of the volume of the rigth circular cylinder a to the volume of the right circular cylinder b

= πr^2h/18hr^2π

= 1:18

Hence, the ratio of the volume of the rigth circular cylinder a to the volume of the right circular cylinder b is 1: 18.
