How many litres will a cylinder pipe hold if it's 1m long and 7cm in diameter take 22/7 as pie

First, we need to calculate the volume of the cylinder. The formula for the volume of a cylinder is:

V = πr²h

where V is the volume, π is pi (22/7), r is the radius, and h is the height.

Since the diameter of the pipe is given as 7cm, we can find the radius by dividing it by 2:

r = 7cm ÷ 2 = 3.5cm

We also need to convert the height from meters to centimeters:

h = 1m = 100cm

Now we can substitute these values into the formula:

V = πr²h
V = (22/7) x 3.5cm x 3.5cm x 100cm
V = 38,465cm³

Finally, we can convert cubic centimeters to liters by dividing by 1000:

V = 38,465cm³ ÷ 1000
V = 38.465 liters

Therefore, the cylinder pipe will hold approximately 38.465 liters of fluid.

To calculate the volume of a cylinder, you need to use the formula V = πr^2h, where V is the volume, π is pi (approximately 3.14), r is the radius of the base, and h is the height.

In this case, the diameter is given as 7cm, so the radius (r) would be half of that, which is 3.5cm or 0.035m (since 1cm = 0.01m). The height (h) is given as 1m.

Now we can substitute these values into the formula to calculate the volume:

V = π × r^2 × h
V = 3.14 × (0.035)^2 × 1
V = 3.14 × 0.001225 × 1
V = 0.00384 m^3

Since 1 liter is equal to 0.001 cubic meters, we can convert the volume to liters:

0.00384 m^3 × (1 liter / 0.001 m^3) = 3.84 liters

Therefore, the cylinder pipe will hold approximately 3.84 liters of liquid.
