Question

How to calculate the volume and the capacity of a cylindrical water tank with the following dimension diameter =150cm and height is250cm

Answer 1

Step-by-step explanation:

radius=diameter/2

r=75cm

h=250cm

volume of cylinder=π×r×r×h

=3.14×75×75×250

=4415625cm cube

Answer 2

volume of cylinder = π r^2h

diameter = 150 cm d = 2r

r=d/2 = 150/2= 75

$volume \: of \: cylinder \: = \pi {r}^{2} h \\ = \frac{22}{7} \times 75 \times 75 \times 250 \\ = 3.14 \times 5625 \times 250 \\ = 3.14 \times 1406250 \\ = 4415625 \: {cm}^{3}$

capacity of tank

volume/1000

$= \frac{4415625}{1000} \\ = 4415.625 \: ltrs$
