Answer:Rs 462
Step-by-step explanation:
Height of frustum, h = 21 cm
Radius of lower end, r = 10 cm
Radius of upper end, R = 20 cm
Volume of frustum = 1/3 * pi * h * (R2 + r2 + Rr)
Put in the values to get the volume as 15.4 litre.
Thus, the cost of milk that can completely fill the bucket is Rs (30 x 15.4) = Rs 462
