radii 20 ft and 14 ft and height 5 ft is full of water.
The drum is emptied into a cuboidal tank of base
73 ft x 44 ft. Find the rise in the height of the
anu.
surfac
50. The
is 77​

Answer 1

Answer:

Volume of frustum = volume of cuboid

⅓pi h(R²+r²+Rr)= lbh

⅓pi×5(20²+14²+20×14) = 73×44×h

⅓22÷7×5(676) = 3212×h

after do it. okk
