Question

Help me out I can’t figure out how to do this

Answer 1

Check the picture below.

`\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=(1)/(4) \end{cases}\implies V=\cfrac{4\pi \left( (1)/(4) \right)^3}{3}\implies V=\cfrac{4\pi(1)/(64)}{3} \\\\\\ V=\cfrac{(4\pi)/(64)}{3}\implies V=\cfrac{(\pi)/(16)}{(3)/(1)}\implies V=\cfrac{\pi }{16}\cdot \cfrac{1}{3}\implies V=\cfrac{\pi }{48}\implies \stackrel{\textit{rounded up}}{V=0.07}`
