Question

8) A tank in shape of a frustum having diameter of top and bottom are 6 m and
10 m respectively. If the height is 3 m then how many litres of oil can be filled
in it. How many drums of 200 l each can be filled?​

Answer 1

Answer:

Step-by-step explanation:

volume- 1/3 * pie * h (r^2 +R^2 + rR)

= 1/3 * 22/7 * 3 ( 9 + 25+ 15)

= 1/3 *22/7 * 3 ( 49)

= 154 m^2

154*1000= 154000 l

154000/200

= 770 drums
