Question

Find the depth of a well radius 3.5m if it's capacity is equal to that of a rectangular tank of dimensions 25 m*11m*7m

Answer 1

Answer:

Volume of cylindrical tank = Volume of rectangular tank

⇒πr

×28×28×h=28×16×11

⇒h=

88

16×11

=2m

∴ Depth of cylindrical tank =2m

Step-by-step explanation:

Answer 2

Answer:

Volume of the cylindrical well = Volume of Rectangular tank

Radius of the cylinder =3.5

Now,

πr²h = l x b x h

22/7 x 3.5 x 3.5 h = 25 x 11 x 7

h = 7 x 25 x 11 x 7 / 22 x 3.5 x 3.5 [ / = ÷ ]

h = 100/2

h= 50m

/ means divide
