Answer:
14.8
Step-by-step explanation:
cos 36° = 12/x
x = 12 /cos 36°
The volume of a cone is V=1/3*pi*r^2*h
Since the value of r is 6 and the value of h is 8, we get:
V=1/3*pi*6^2*8
V=1/3*pi*36*8
V=12*pi*8
V=96pi
V=301.5928947
So the exact volume of the cone is 301.5928947 m^3
The approximate value of the volume rounded to the nearest tenth is 301.6 m^3
Step-by-step explanation:
y = 5/2 x + 3
x = 5/2 y + 3
5/2 y = x - 3
y = 2/5 x -6/5
