Answer:
The height of the cone is 0.5
Step-by-step explanation:
The formula of a cone is:
V= 1/3 πr² h
where r = 4 inches
V = 8 cubic inches
Now plug the values in the formula:
8 = 1/3 * 3.14 *(4)^2 *h
8 = 1/3 * 3.14 * 16 *h
8 = 50.24/3 * h
Now shift the R.H.S to the L.H.S
8 * 3/50.24 =h
24/50.24 = h
0.477707 =h
Rounding off to the nearest tenths place
=0.48
=0.5
Thus the height of the cone is 0.5 ...
