# How To Find Surface Area Of Sphere?

## What is the formula for finding the surface area of a sphere?

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

## What is the total surface area of a sphere?

A sphere with radius r has a volume of 4 3 π r 3 \frac{4}{3} \pi r^3 34πr3 and a surface area of 4 π r 2 4 \pi r^2 4πr2. A sphere has several interesting properties, one of which is that, of all shapes with the same surface area, the sphere has the largest volume.

## How do you find the surface area and volume of a sphere?

Sphere Surface Area and Volume –

## What is the formula of lateral surface area of sphere?

Common Lateral Surface Area Formulas

The lateral surface area of a sphere is 4(pi)r^2. The lateral surface area of a cone is (pi)rs. And the lateral surface area of a rectangular box is 2h(l+w).

## What is the area of the sphere?

Therefore, the Surface Area of a Sphere with radius r equals 4πr2 .

## What is the formula for area?

Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

## How do you derive the formula for a sphere?

Volume of a Sphere, How to get the formula animation –

## What is the formula of hollow sphere?

To determine the volume of a sphere, we use the formula 4/3πr^3. So, to find the volume of a hollow sphere, we must subtract the volume of the hollow region from the volume of the overall sphere. Let’s call the radius of the overall sphere r1 and the radius of the hollowed region r2. Thus, we get 4/3π*r1^3 – 4/3π*r2^3.

## What is the formula for the surface area of a hemisphere?

The surface area of a sphere of radius r is 4 π r2. Half of this is 2 π r2. If this is what is meant by the surface area of a hemisphere then 2 π r2 = 1062.

## What is the formula of volume?

Calculating Volume

The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times. This results in the formula: Volume = side * side * side.

## What is the curved surface area of a sphere?

Curved Surface Area: The area of the outer surface of the hemisphere is called the curved surface area. From the surface area of a sphere, we can easily calculate the surface area of the hemisphere. The curved surface area of a hemisphere = 2πr2 square units.

## What is the formula to finding the volume of a sphere?

To calculate the volume of a sphere, use the formula v = ⁴⁄₃πr³, where r is the radius of the sphere. If you don’t have the radius, you can find it by dividing the diameter by 2. Once you have the radius, plug it into the formula and solve to find the volume.
