Answer 1

Question:

What is the volume of a sphere with a radius of 3.16 cm, rounded to the nearest tenth of a cubic centimeter?​

Solution:

Remember that the formula for the volume of the sphere is:

$V\text{ = }\frac{4}{3}\pi r^3$

Where r is the radius of the sphere. Now, if we have a sphere with a radius of 3.16 cm, then its volume is:

$V\text{ = }\frac{4}{3}\pi(3.16)^3\text{ = }132.175\approx132.18$

Then, we can conclude that the correct answer is:

$V\text{ = }132.175\approx132.18cm^3$
