Question

a circular well is dug .its diameter 3.5 m its depth is 6 m what is the lateral surface area of the waell ?what is the volume of the earth removed to make the well?

Answer 1

Answer:

Step-by-step explanation:

diameter= 3.5 m ( so radius = 1.75 ) and height = 6 m

lateral surface =2πrh= 2 x 22/7 x 1.75 x 6 = 66

(well if u use 3.14 then it goes like this 2 x 3.14 x 1.75 x 6 = 65.94 )

volume = πr²h = 22/7 x 1.75 x 1.75 x 6 = 57 .75

( if u use 3.14 well then again for my money  it goes like this 3.14 x 1.75 x 1.75 x 6 = 57.69)

hope you like this ( thank the hell )
