A building has 144 cylindrical pillars,all of the same size.If the diameter of each pillar is 2m and each has a height of 2cm,find the volume bound in each of the pillars?

Answers

Answered by TPS

diameter of each pillar = 2m
radius = diameter ÷ 2 = 2 ÷ 2 = 1m
height = 2cm = 0.02m

$Volume\ of\ each\ pillar= \pi r^2h= \pi *1^2*0.02=\boxed{0.0628\ m^3}$

Himansh: answer is wrong

TPS: what is wrong in it?

Himansh: its a psa sample paper question

TPS: okay but what is wrong in the answer?

Himansh: given by my school to everyone

Himansh: the options are given for this question are a)22 cubic meter b)3168 cubic meter c)152 cubic m d) 154 cubic m.

Himansh: It's may be possible that the options are wrong

Himansh: please tell me the answer tomorrow is my psa exam.

TPS: is the height 2cm?

TPS: have you written the question correctly?

Answered by Aaeesha

Diameter of each pillar =2m = 200 cm

Radius, r of each pillar = 100 cm

Height, h = 2 cm

Hence, Volume occupied by each pillar = πr^2h = 3.14*(100)^2*2 = 62800 cm^3

Himansh: this is even wong according to the psa sample paper options

Himansh: answer should be come in cubic meter.
