The volume is 314.286 cm^3 approximately
Step-by-step explanation:
The ABC have sides of measure 12,5&13 respectively
and it is revolved about the side 12 cm so it will be in the bottom so the height will be12
cm
h=12cm
r=5cm
V= 1/3πr^2h
= 1/3 * 22/7 * 5 * 5 * 12
= 22/7 * 25 * 4
= 22/7 * 100
= 2200/7
= 314.286 cm^3 approximately (because 22/7 is a non-terminating and decimal as it has no effect with 0 when it's divided)
