Question

The outer edge radius of a 21 m deep well to be constructed is 10.5m and the inner radius for construction is 10m. Find the volume of construction work

Answer 1

Dear Student,

◆ Answer -

Volume of construction work = 676.5 m^3

● Explanation -

Volume of construction work is given by -

Volume of construction work = volume of outer cylinder - volume of inner cylinder

Volume of construction work = πR²h - πr²h

Volume of construction work = πh (R²-r²)

Volume of construction work = 22/7 × 21 × (10.5² - 10²)

Volume of construction work = 22 × 3 × (110.25 - 100)

Volume of construction work = 66 × 10.25

Volume of construction work = 676.5 m^3

Hence, volume of construction work is 676.5 m^3.

Thanks dear. Hope this helps you...
