if its diameter is 12, then its radius is half that or 6.

\textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=6 \end{cases}\implies V=\cfrac{4\pi (6)^3}{3}\implies V=\cfrac{4}{3}\cdot \pi \cdot 6^3 \\\\\\ V=\cfrac{864}{3}\cdot \pi \implies V=\cfrac{864}{3}\cdot 3.14\implies V\approx 904.32~cm^3

Zoe used 3/8 of her ribbon to wrap a present. If she uses 9 feet of ribbon for the present how much ribbon did Zoe have it first
MArishka [77]

Let the total ribbon Zoe had was x feet.

Out of x feet, she used 3/8 part of it.

Hence, \frac{3x}{8}

3/8 part of the original ribbon is equal to 9 feet.

Hence, we get

\frac{3x}{8} = 9

=> Multiply 8 on both sides.

3x=72

Divide both sides by 3

\frac{3x}{3}=\frac{72}{3}

x=24 ft

Zoe had 24 feet of ribbon in starting... Answer
