Step-by-step explanation:
HEY HERE IS THE ANSWER FOR YOUR QUESTION............
First let us Find the possible values from the given ones:-
π r^2 = 100
keep the π as it is don't substitute it's value
r^2 = 100 / π
r = 10 / √π
NOW LETS FIND THE VOLUME OF THE CYLINDER
π r^2 h = π * 100 / π * 3
π and π will get cancelled.
= 300 cm^2
NOW LETS FIND THE HEIGHT OF THE CONE
1 / 3 π r^2 h = 1 / 3 π* 100 / π * h = 200
again π and π will get cancelled
100 h = 200 * 3
h = 200 * 3 / 100
h = 6 cm
Now the total height of the figure is height of cone + height of cylinder
= 6 +3
= 9 cm
so this is your answer for the question...........
so the height of the figure is = 9 cm.
