Please help me on this question (answer all parts please)

SOLUTION:

Case: Volume of Sphere

Method:

a) The volume of a sphere whose diameter, d= 28in

The radius,

r= 28/2

r= 14 in

The Volume, therefore:

$\begin{gathered} V=\frac{4}{3}\pi r^3 \\ V=\frac{4}{3}\pi\times14\times14\times14 \\ V=11494.04\text{ }cubic\text{ }inches \end{gathered}$

b) When half of the volume is used,

$\begin{gathered} V=\frac{1}{2}V_0 \\ V=\frac{1}{2}\times11494.04 \\ V=5747.02\text{ }cubic\text{ }inches \end{gathered}$

c) The radius of the halved volume

$\begin{gathered} V=\frac{4}{3}\pi r^3 \\ 5747.02=\frac{4}{3}\pi r^3 \\ r^3=\frac{3\times5747.02}{4\pi} \\ r^3=1372 \\ r=\sqrt[3]{1372} \\ r=11.11\text{ }inches \end{gathered}$

Final answer: (To 2 d.p)

a) 11494.04 cubic inches

b) 5747.02 cubic inches

c) 11.11 inches
