Introduction to Disk Method Calculator

Disc method calculator is an online calculator which helps you to calculates the solid of revolution’s volume in seconds. volume by disk method calculator uses disk method formula to compute complex problems.

If you are facing trouble with any disk method problem, you can use this disc calculator, which will assist you to calculate your given function in no time. To continue, you must read the basics and disc method formula used by the disc integration calculator.

You can also use cylindrical shells method calculator to calculate the volume of revolution when integrating along perpendicular to the axis of revolution. And washer method solver to find the volume of solid of revolution online.

When a two-dimensional shape circles around a line or axis, tri solids of revolution are formed. The disc technique is named after the fact that all solids of revolution contain circular discs and cross-sections. Cones, Cylinders, and spheres are some instances of solids of revolution.

The disc method is similar to how an egg slicer works. An egg slicer slices a hard-boiled egg into discs. You can reassemble the egg by stacking those pieces on top of one another. The disc method divides a solid into insignificantly thin discs using mathematics.

The slices are always perpendicular to the x-axis for a period of revolution around the x-axis. The area of each slice is determined using the disc approach. Then, using integration, it sums up all of those areas across the length of the solid, producing the solid's volume.

Frequently Asked Questions

In calculus, what exactly is the disc method?

Disc integration, commonly known as the disc method in integral calculus, is a method for estimating the volume of a steady material's solid of revolution when trying to integrate with an axis parallel to the revolution axis.

Who came up with the disc technique?

A washer is a disc with a hole punched out in the middle. Both an inner radius r1 and an outer radius r2 are required in the formula for a washers volume.

Related: You can esily calculate Double and Triple integrands step by step by using our double integral calculator with steps free and online triple integral calculator.

Is Disk and Washer Method the Same?

The washer method deals with the complex shapes of solid, whereas the disk method is used to find volume of a disk shape. Therefore, both are different concepts.

What is the solid's volume?

A solid's volume is an indicator of how much space it occupies. The number of unit cubes needed to fill the solid is used to calculate it.

To find the volume of slice of a solid use volume disk method calculator step by step.

Which of the following objects is a rotating solid?

A solid of revolution is a solid object made by rotating a plane curve along a straight line (the revolution axes) that present in the original plane in engineering, mathematics, and production.

What is the disk method formula?

In calculus, the disk method is a slicing technique that is used to find the volume of a solid by its revolution in a cylinder or a disk. It uses the cross sectional area of the new shape. The disk method formula is,

$$ V \;=\; \int_a^b R(x)^2 dx $$


R(x)2= is the square of distance between the function and the axis of rotation.

Use disk and washer method calculator to get step by step results without any error.

What is the difference between disk and washer method?

The disk method finds the volume of revolution by using infinitesimally thick slices in the shape of disk. Whereas, the washer method used the two radii, inner and outer. It finds the volume of revolution by integration of difference between area of inner and outer slice. Disk washer method calculator helps you to calculate them online.

What is circular disk method?

The disk method is also known as circular disk. It is because it involves circular shape infinitesimal thick disks. It finds the volume of the solid by decomposition and rotation along an axis. The formula is,

$$ V \;=\; \int_a^b R(x)^2 dx $$


R(x)2= is the square of distance between the function and the axis of rotation

You can use our circular disk method calculator to get instant results online.
