At first, we will find the volume of the cone and the volume of the sphere, then subtract them to find the answer

The rule of the volume of the cone is

$V_c=(1)/(3)*\pi* r^2* h$

Since the height of the cone is 1 cm and its radius is 3 cm, then

h = 1 and r = 3

Substitute them in the rule above

$\begin{gathered} V_c=(1)/(3)*\pi*(3)^2*(1) \\ V_c=(1)/(3)*\pi*9*1 \\ V_c=3\pi \end{gathered}$

The formula of the volume of the sphere is

$V_(sp)=(4)/(3)*\pi* r^3$

Since the diameter of the sphere is 3 cm, then

$\begin{gathered} r=(1)/(2)*3 \\ r=(3)/(2) \\ r=1.5\operatorname{cm} \end{gathered}$

Substitute it in the formula above

$\begin{gathered} V_(sp)=(4)/(3)*\pi*(1.5)^3 \\ V_(sp)=4.5\pi \end{gathered}$

Noe subtract them to find the answer

$\begin{gathered} V=4.5\pi-3\pi \\ V=1.5\pi \end{gathered}$

The amount of the extra soap is

$1.5\pi cm^3$
