A circular well with a diameter of 2 metres, is dug to a depth of 14 m

1.	A circular well with a diameter of 2 metres, is dug to a depth of 14 metres. What is the volume of the earth dug out? A. 32 m3 B. 36 m3 C. 40 m3 D. 44 m3
Answer» Given that, Diameter of the circular well = 2 m Radius = 1 m Height = 14 m Therefore, Volume of cylindrical well = \(\pi r^2h\) = \(\frac{22}{7}\times1\times1\times14\) = 44 m³ Hence, option D is correct

A circular well with a diameter of 2 metres, is dug to a depth of 14 metres. What is the volume of the earth dug out? A. 32 m3 B. 36 m3 C. 40 m3 D. 44 m3

Answer»

Given that,

Diameter of the circular well = 2 m

Radius = 1 m

Height = 14 m

Therefore,

Volume of cylindrical well = \(\pi r^2h\)

= \(\frac{22}{7}\times1\times1\times14\)

= 44 m³

Hence, option D is correct
