Answer 2

Answer:

height of cone = 12cm

radius of lower end (r) = 8cm

radius of upper end (R) =18cm

therefore,

capacity of bucket = volume of bucket

= 1/3πh(r^2+R^2+r×R

=1/3×22/7×12{(8)^2+(18)^2+8×18}

=88/7(164+324+144)

= 46816/7

=6688

So,

Capacity of bucket is 6688cm^3

cost of milk@25rupees = 6688×25

=167200 rupees
