Answer:

32 pi m^2

Step-by-step explanation:

The surface area of a cylinder is given by

SA = 2pi r^2 + 2 pi rh

   The diameter is 4 meters so the radius is 1/2 of the diameter = d/2 = 2 meters

SA = 2 * pi * (2)^2 + 2 pi *2*6

    = 8pi +24pi

   = 32 pi m^2

Please help with Volume
Archy [21]

Given:

Length of the cuboid tank = 4 m

Breadth = 2.5 m

Height = 2.4 m

One third of the tank is filled with water.

1 cubic meter = 1000 liters.

To find:

The quantity of the water in the tank.

Solution:

Volume of a cuboid is:

V=l\times b\times h

Where, l is length, b is breadth and h is the height.

The volume of the tank is :

V=4\times 2.5\times 2.4

V=24

Volume of tank is 24 cubic meter.

One third of the tank is filled with water. So, the volume of the water is

\dfrac{24}{3}=8

The volume of water is 8 cubic meters.

We have,

1 cubic meter = 1000 liters.

8 cubic meter = 8000 liters.

Therefore, the quantity of the water in the tank is 8000 liters.
