Question

in a modern building a concrete column is cylindrical in shape, having a diameter of 1 m and height of 21 m What would be the cost of concrete for the column at Rs 260 per cubic meter​

Answer 1

The cost price of the concrete for the column at Rs 260 per cubic meter is  618.9 rupees.

To calculate the cost of concrete for a cylindrical column, we need to know the volume of the column. The volume of a cylinder is given by the formula:

V = πr²h

where V is the volume, r is the radius, h is the height, and π is pi.

Given that the diameter of the column is 1 meter, we can calculate the radius as 0.5 meters. And the height is 21 m.

So, the volume of the column is:

V = π (0.5)² 21 = 3.14 * 0.25 * 21 = 2.365 cubic meter

So the cost of the concrete for the column would be 2.365 * 260 = 618.9 rupees.

So, the cost of the concrete for the column at Rs 260 per cubic meter would be 618.9 rupees.
