Question

An oil candle globe made of​ hand-blown glass has a diameter of 25.8 cm. What is the volume of the​ globe? Use 3.14 for .

Answer 1

globe meaning a sphere, and since it has a diameter of 25.8, that means its radius is half that, or 12.9

`\textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=12.9 \end{cases}\implies V=\cfrac{4\pi (12.9)^3}{3}\implies \stackrel{ using~\pi =3.14 }{V\approx 8987.47}`
