Answer:
GIVEN: width of embankment = 7mts
its inner radius (r) = 7 ms and outer radius (R) = 7+7=14mts
volume of earth dug out = vol of soil in embankment
πr²h = vol of soil in embankment
22/7×7²×12000 = π h ( R²- r² )
1848000 = 22/7 × h × ( 14²-7² )
1848000 × 7/22 = h x 147
h = 84000 x 7 / 147
h = 588000 / 147
h = 4000 mts
Akshiti:
width of embankment is 3.5m
then put 3.5 in the place of 7.
the answer when the width of the embankment is 3.5 will be 800mts.
please mark it as the brainliest answer
from where 12000 come
