The radius of the sphere is half of the diameter, which is 10 centimeters.
The volume of a sphere is given by the formula V = (4/3)πr^3, where r is the radius.
Substituting the values we have:
V = (4/3) x 3.14 x 10^3
V = 4.19 x 10^3
Rounded to the nearest tenth, the volume of the sphere is 4,188.8 cubic centimeters.

Isn't asking for an accuracy of a tenth and then suggesting to use 3.14 for π sort of silly, don't you think. After all , every calculator in 2023 has π
build in as a constant.
anyway .....
volume = (4/3) π 10^3 cm^3
= 4,186.7 using 3.14 for π
= 4,188.8 using built-in π
build in as a constant.

You're right, it would be more accurate to use the built-in constant for pi on a calculator. However, some math problems or exams may require the use of a specific value for pi.
Thanks for providing the more accurate answer with the built-in constant for pi!
