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

Step-by-step explanation:
So this is a ratio questions basically.
We're sharing the pens in the ration 5:3
$4.00 / 8 = $0.50
$0.50 x 5 = £2.50
$0.50 x 3 = $1.50
