Question

Find the volume of the Earth dug out from a circular well of 24.5m deep and 3m radius​

Answer 1

Answer:

Volume of the Earth dug out = Volume of the circular well = (22/7 ×3²×24.5) m³ =( 22/7 ×9×24.5) m³ =693 m³

Answer 2

Answer:

PLEASE MARK THIS ANSWER AS BRAINLIEST IF IT IS HELPFUL TO YOU :)

Given: h=24.5 m and r=3 m

Volume of circular well = π$r^{2}$h

Volume of circular well = 22/7*3*3*24.5

Volume of circular well = 22/7*9*245/10

Volume of circular well = 22*9*35/10

Volume of circular well = 6930/10

Volume of circular well = 693 sq. m
