Question

A well with 14m diameter and 8 m deep is dug and evenly spread onto a width of 21cm find tge height og embankment

Answer 1

Volume of earth dug out = 22/7*7*7*8 = 1232 cm³

Area of embankment = π (R² - r²)

= 22/7 * (28²- 7²)

= 22/7 * 35 * 21

= 2310 m²

Therefore,

Height of embankment 1232/2310 * 100 cm = 53.3 cm ANSWER
