Question

Rain water from a horizontal roof 11m x 6 m drains into a vessel in the form of
a frustum of a cone. The height of the vessel is 1.4 m and the radii of its top and
bottom are 0.9 m and 0.6 m. If the vessel is just full, find the rainfall in
centimetres..​

Answer 1

Answer:

The measure of rainfall in cm is 3.8cm

Step-by-step explanation:

Volume of cuboid = Volume of frustum

11×6×x. = 1/3πh(r1² + r2² + r1×r2)

x. =. 0.038metre

= 3.8cm
