### What is a hemisphere definition for kids?

A hemisphere is half of a sphere, or ball. People use the word to describe one half of Earth. Geographers, or people who study Earth, have divided the planet into two sets of two hemispheres. These are the Northern and Southern hemispheres and the Eastern and Western hemispheres.

### How do you solve a hemisphere?

How do I calculate the surface area of a hemisphere?

1. Square the radius of the hemisphere.
2. Multiply by the number pi.
3. Multiply by three.

What is sphere and hemisphere?

A circular shaped ball with a diameter or radius is called a sphere. A diameter which is a straight line through the center of a sphere and with the end points on the boundary is called its diameter. The section of the sphere by the plane is called a hemisphere.

#### What is hemisphere short answer?

The word “hemisphere” is usually used to refer to halves of the Earth, but it is also used to identify the halves of the brain. The brain is divided down the middle into the right and left hemispheres. Each brain hemisphere is considered to be specialized for certain behaviors.

#### What is a sentence for hemisphere?

What is hemisphere class 10th?

A hemisphere is obtained when we cut the sphere into two equal halves. The total surface area of hemisphere will be equal to the sum of its curved surface area and the base area of hemisphere.

## How do you find the radius of a hemisphere?

How can I calculate radius of a hemisphere? You would have to know other information. If, for example, you know the surface area (A) of the hemisphere, divide it by 2π, then find the square root of that number. Thus, r = √(A / 2π).

## Why is it called hemisphere?

#### What is the formula for a hemisphere?

x 2 + y 2 + z 2 = R 2. The Cartesian form or equation of a hemisphere with the radius “R” at the point (x 0, y 0, z 0) is written as. (x-x 0) 2 + (y- y 0) 2 + (z- z 0) 2 = R 2. Therefore, the spherical coordinates of the hemisphere are given as follows. x = r cos θ sin ∅. y = r sin θ cos ∅. z = r cos ∅.
