Question

a drum diameter of 13 M and depth 35 M is half filled with water find the volume of water inside the drum

Answer 1

Answer:

where r is the radius of the cylinder and h is the height of the cylinder. Since the water forms the shape of a cylinder inside the well, we will take the values of radius and height as follows, r=6.5 mtr and h=17.5 mtr. Substituting these values in the formula for volume of the cylinder, we get

V=3.14×(6.5)2×(17.5)

Simplifying the above equation, we get

V=3.14×42.25×17.5=2321.6375 mtr3

Therefore, the volume of the water inside the well is 2321.6375 cubic mtr
