Question

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 1

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
