From V= 4/3*pi*r^3
<span>dV/dt = 4pi(r^2)dr/dt </span>
<span>so when dV/dt=30 and r = 19 </span>
<span>30 = 4pi(361)dr/dt </span>
<span>dr/dt = 30/[4pi(361)] </span>
<span>now in </span>
<span>A = 4pir^2 </span>
<span>dA/dt = 8pi(r)dr/dt </span>
<span>= 8pi(19)*30/[4pi(361)] </span>
<span>= you finish it.</span>
<span>HOPE THIS HELPS.

If she chose the color she would have 12 options left.
Answer:
-1
Step-by-step explanation:
15x-8x-2=-9
Or, 7x=-9+2
Or, 7x=-7
Or, x=-7/7
Or, x =-1
Yes it is, if you look on a number line, the -34 is farther left than the -9
The perpendicular bisector of RT is B. SU.
