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

Answer 1

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.
