Question

how much water will a tank hold if interior diameter of tank is 1.6 m and it's depth is 0.7 m​

Answer 1

here water tank is cylinder,

diameter = 1.6 ,r = d/2 = 1.6/2 = 0.8m

height = 0.7m

volume of cylinder is πr²h

22/7 x 0.8 x 0.8 x 0.7

= 9.856/7 = 1.408m³

hope it help you

Answer 2

the amount of water hold = volume of tank

= r = 0.8m

h = 0.7m

πr^2h=

$\pi \times 0.8 \times 0.8 \times 0.7$

= 1.408m^3
