Question

The following sphere has a diameter of 7 cm what is the volume of the sphere use 3.14 for pie and round your answer to the nearest 10th

Answer 1

Answer: We have to calculate the volume of a sphere that has a diameter of 7cm, the formula for volume that we would use is as follows:

$V(r)=\frac{4}{3}\pi r^3\rightarrow(1)$

Using equation (1) , and substituting the unknowns, the volume is determined, the steps are as follows:

$\begin{gathered} r=7cm \\ \pi=3.14 \\ \\ V(7cm)=\frac{4}{3}(3.14)(7cm)^3 \\ \\ V(7cm)=1,436.03cm^3 \end{gathered}$

The volume is 1436.03 cubic-centimeters.
