Question

please give this answer in proper method​

Answer 1

HI DEAR,

The well has height = 20 m

radius of well = 3.5 m

Volume of earth dig out = πr²h = π×3.5×3.5×20

The platform's volume = l×b×h

22×14×h

THE VOLUME OF WELL AND PLATFORM IS SAME AS EARTH FROM WELL IS EVENLY SPREAD ON THE PLATFORM..

22×14×h = 22/7 × 3.5×3.5×20

h = 2.5 m

HOPE IT HELPS..

Answer 2

Answer:

Step-by-step explanation:

HI DEAR,

The well has height = 20 m

radius of well = 3.5 m

Volume of earth dig out = πr²h = π×3.5×3.5×20

________________________________________________________

The platform's volume = l×b×h

22×14×h

THE VOLUME OF WELL AND PLATFORM IS SAME AS EARTH FROM WELL IS EVENLY SPREAD ON THE PLATFORM..

22×14×h = 22/7 × 3.5×3.5×20

h = 2.5 m
