Ramesh wants to make a frustum-shaped tumbler. He chooses radii 3 cm and 6 cm and wants the capacity to be exactly 396 cm^3 (use π = 22/7). Find the required height of the tumbler, in cm.

Question

Accepted Answer

6. V = 1/3*22/7*h*(36 + 9 + 18) = 1/3*22/7*h*63 = 22/7*21*h = 66h. Set 66h = 396 -> h = 6 cm.

Ramesh wants to make a frustum-shaped tumbler. He chooses radii 3 cm and 6 cm and wants the capacity to be exactly $396 cm^{3}$ (use π = $\frac{22}{7}$ ).
