# What is the area of the sphere?

## What is the area of the sphere?

4*Pi*R2

And the formula for the surface area of a sphere of radius R is 4*Pi*R2.

## What is the area of the cylinder?

A cylinder’s volume is π r² h, and its surface area is 2π r h + 2π r². Learn how to use these formulas to solve an example problem.

**What is the formula of a cylinder and sphere?**

The formula for the volume of a sphere is 4⁄3πr³. For a cylinder, the formula is πr²h.

### What is the relation between sphere and cylinder?

Note : The volume of a sphere is 2/3 of the volume of a cylinder with same radius, and height equal to the diameter.

### What is a formula of a cylinder?

The formulas of cylinder are: Total surface area = 2πr(r+h) square units. Volume of cylinder = πr2h cubic units.

**What is the surface area of a circle?**

The area of a circle is pi times the radius squared (A = π r²).

## What is the formula for spheres?

The line that connects from the center to the boundary is called radius of the square. You will find a point equidistant from any point on the surface of a sphere….Formulas of a Sphere.

## What is the total surface area of cylinder and cone?

Lateral Surface Area = Perimeter of base × height = 2πrh = πdh. Total Surface Area = Lateral Surface Area + Area of bases = 2πrh + 2πr² = 2πr (h+r)

**How many spheres are in a cylinder?**

The maximum density for packing equal spheres is about 74%, not 64%. This happens when the spheres form either a face-centered cubic lattice (FCC) or a hexagonal close packed lattice (HCP). Each sphere is then in contact with 12 other spheres. spheres in the container.

### What is the surface area of a cylinder?

### How to determine the area of a semisphere cut by a cylinder?

Determine the area of a semisphere cut by a cylinder Related 0 Find surface area by calculating surface integrals 3 Find the surface area of the portion S of cone within cylinder 1 Surface integral, area of a part of a sphere inside a cylinder 2 Surface area of paraboloide inside sphere 0

**Is the surface area of a cone the same as a sphere?**

No, it does not work for the cone. But we do get the same relationship for the sphere and cylinder ( 2 3 vs 1) And there is another interesting thing: if we remove the two ends of the cylinder then its surface area is exactly the same as the sphere:

## What is the volume of a sphere vs cylinder?

Volume of a Sphere vs Cylinder Now let’s fit a cylinder around a sphere. We must now make the cylinder’s height 2r so the sphere fits perfectly inside. So the sphere’s volume is 4 3 vs 2 for the cylinder
