Answer:
Option D
It will take 33.93 minutes to melt
Step-by-step explanation:
Because the icicle is the same shape as a cone, the volume of the icicle will be equal to that of the cone
Volume of a cone is given as [tex]v =\frac{\pi r^{2}h}{3}[/tex]
hence the volume of the cone is [tex]v =\frac{\pi \times4.5^{2}\times 120}{3}= 2544.69 mm^{3}[/tex]
if the icicle drips at 75 millimeters cubed per minute, to get the time it will take to completely melt, we will have ti divide the volume by the rate of melting.
This will be given as [tex]v=\frac{2544.69}{75}=33.93 minutes[/tex]
