Let's do this question, the radius and height of a cylinder are in the ratio, three is to do and its
volume is one nine four zero four centimetre cube find its radius and height was the video.
Give it a try and then let's do it together.
All right.
We are back.
Let's do it together over here.
It's given that are by X is equal to three by two right now.
Let's take our three X and it's S two X right now.
Volume of a cylinder is biased coverage right now.
Let's substitute the values that we have got over here that it's equal to buy into 3x square in the
two X, right.
That simplifies to eighteen by excuse.
All right, now this pie can be taken as 22 by seven, right, because we can approximate pie as 22
by seven.
Let's substitute that over here.
So this becomes 18 in the 22 by seven to execute.
All right.
Now, over here, it's given that the volume is one nine four zero four centimeter cube.
Right.
So let's equate this and the value given over here to 18.
The 22 by seven in the cube is equal to one nine four zero four.
And you can simplify this as 22 by seven excusive is equal to one zero seven eight or KUBIS seven and
to forty nine.
And that gives you X as seven.
So the answer is the radius is three in the X that's twenty one centimeter and the height is doing the
X that's 14 centimeters.
