Answer:
9/40 kg
Step-by-step explanation:
Given:
He needs 5/8 kg but he first tips only 2/5 kg
additional flour needed,
= amount needed - amount already tipped
= 5/8 - 2/5
= 25/40 - 16/40
= (25 - 16) / 40
= 9/40 kg
Let the original volume be pi *r^2* h where r = radius and h = height.
The new volume will be pi *(2/5 r)^2 * 4h = pi*4/25 r^2 4h
pi*4/25r^2 * 4h / pi r^2 h = 4/25 * 4 = 16/25
The volume has been reduced by factor of 16/25.
