Find the volume of the right cone. round your answer to one decimal.

Hello from MrBillDoesMath!

 1206.4

Discussion: From Plane Geometry the volume of a right cone is

(Pi * r^2 * h)/3      

where "r" is the base radius and "h" is the height involved. In our case

r = 12 and h = 8  (I not exactly sure about the "h"  value. The number shown in the diagram is not completely clear).

(Pi * 12^2 * 8) /3 =   (Pi * 144 * 8)/3

As 3 divides 144, 48 times this formula is equivalent to

Pi*  48 * 8   = Pi * 384

which is 1206.371579 ... rounded up to one decimal gives  1206.4
