Question

How much water will be contained in a cylinder cement tank , if diameter of the tank is 7cm and height is 6 times the radius​

Answer 1

Answer:

Capacity of Tank = 808.5 cubic meters

Step-by-step explanation:

The tank is in cylindrical shape.

Hence capacity of tank = volume of cylinder = πr²h

r - radius of the base

h - height of the cylinder.

Given that

Diameter of the cylinder = 7 m

Radius = r = Diameter / 2 = 7 / 2 = 3.5 m

Height = 6 times the radius = 6r = 6 * 3.5 = 21 m

Capacity of Tank = πr²h

Substituting above values we get

Volume (or Capacity of tank) = 22*3.5*3.5*21/7 = 22*3.5*3.5*3

= 808.5 cubic meters

hope..it..helps..!

Answer 2

Answer:

808.5 cubic cm

Step-by-step explanation:

Given that

height = 6 x radius

let radius be r and height be h

h = 6r

h = 6 x 3.5 = 21 cm

radius = 3.5 cm

now,

volume = pie x r x r x h

= 22/7 x 3.5 x 3.5 x 21

=22 x 3.5 x 0.5 x 21

= 808.5 cubic cm
