Answer:
d=8.0 meters
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h
We are given the volume and the height
117.23 and the height 7
117.23 = 1/3 *3.14 *r^2 * 7
117.23 = 7.3266666666 *r^2
Divide each side by 7.3266666666
117.23/7.3266666666 = 7.3266666666 *r^2/7.3266666666
16.00045496 = r^2
Take the square root of each side
sqrt(16.00045496) =sqrt( r^2)
4.000 = r
We found the radius but it wants the diameter
d = 2*r
d =2*4.0
d=8.0 meters
-2x+1/2y=18
xint is where y=0
-2x+0=18
-2x=18
divde by -2
x=-9
xint isi (-9,0)
Answer:
17/13
Step-by-step explanation:
r(6) = 3(6) - 1 = 17 and s(6) = 2(6) + 1 = 13.
Then (r/s)(6) = 17/13.
