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".

We are given with the polynomial function <span>f(x) = 3x3 + 8x2 − 87x + 28 and is asked for the roots of the equation. The function given is a third order polynomial because the highest degree among the polynomials is 3.
In this case, to find the roots of the equation, we equate the function to zero, and then find the values of x.
Thus, the equation becomes </span><span>3x3 + 8x2 − 87x + 28 = 0. We can use an online polynomial finder to determine the roots of the equation. There are three roots of this equation since the order of this polynomial is 3 which are the following:
</span><span><span>Root 1: -7
Root 2: 1/3
Root 3: 4
All factors are real numbers, not imaginary.
