Question

A tanker is made by joining 2 hemisphere of radius 3.5m each to each of the ends of a cylinder having height 27m and radius 7m. Petrol from the completely filled tanker is transformed into hemispherical vessels of radius 1.75m. Find the number of hemispherical vessels​

Answer 1

Answer:

n = 1339

Step-by-step explanation:

Vol. of petrol in tanker = n × vol. of hemispherical vessels

:. Vol. of cyl. + 2(Vol. of hemisphere) = n × Vol. of hemispherical vessels

:. PI×r^2×h + 2(2/3×PI×r^3) = n × 2/3×PI×r^3

:. n = 1339
