Using 3.14 for π, what is the volume of a ball with a diameter of 7 centimeters

Mathematics

vampirchik [111]3 years ago
4 0
If the diameter is 7, the radius is half that or 3.5, thus

\bf \textit{volume of a sphere}\\\\
V=\cfrac{4\pi r^3}{3}~~
\begin{cases}
r=radius\\
-----\\
r=3.5
\end{cases}\implies V=\cfrac{4\pi (3.5)^3}{3}\implies V=\cfrac{171.5\pi }{3}

Artemon [7]
3 9/100 would be written as a decimal like this, 3.09. You say three and nine one hundredths. The 9 has to be in the hundredths place, so you put a 0 in front of it. And since the 3 is hole, you put it in front of the decimal point.
