<h3>What is the sphere?</h3>

A sphere is a 3D geometrical object which has a radius and becomes a point that revolves around a fixed point called the center.

A sphere has surface area and volume based upon the radius of the sphere.

For example, if you have a sphere of radius r then its surface area will be 4πr² and volume will be (4/3)πr³.

The table tennis ball is the form of a sphere.

Given that,

The diameter of a table tennis ball is 20

Radius(r) = 20/2 = 10 mm

Surface area of an sphere = 4πr²

So,

Area = 4π(10)² = 1256.64 mm².

Hence "The surface area of the table tennis ball will be around 1256.64 mm²".

Tell whether each set of ordered pairs representd a function. Justify your answers.
Alenkinab [10]
To be a function every x should have only one y-value.
<span>a. (0,0), (1,1), (2,2), (3,3), (4,4) - We do not see repeating values of x, so  it is a function

</span>b. (0,8), (1,6), (2,4), (3,2), (4,0)- We do not see repeating values of x, so  it is a function

<span>c. (3,0), (3,1), (3,2), (3,3), (3,4) - We see repeating value of x, that means that one value of x corresponds many values of y , so it is not a function.</span>
