Answer:

252π or 791.7 mm³/h

Step-by-step explanation:

The volume of a cylinder is given by

$V = \pi r^2h$

We desire to find the volume rate, that is, $\dfrac{dV}{dt}$

$\dfrac{dV}{dt} = \dfrac{dV}{dr}\cdot\dfrac{dr}{dt}$

dr/dt is the rate of change of the radius which is 7 mm/h.

dV/dr is derived by differentiating the volume equation, yielding

$\dfrac{dV}{dt} = 2\pi rh$

At r = 12 mm and h = 1.5 mm,

$\dfrac{dV}{dt} = 2\pi\times12\times1.5\times7 = 252\pi = 791.7$

S = n(a1 + an)/2
2S = n(a1 + an)
2S = na1 + nan
nan = 2S - na1
an = (2S - n a1)/n

Yes, they can add up to 180 degrees. Say one angle is 65 degrees, and the other one is 115 degrees. That would equal to 180 degrees.
Hope this helps.

G(h(0)) = 20

h(x) = x+4
h(0) = 0+4
h(0) = 4

g(x) = 5x
g(h(0)) = g(4) = 5(4) = 20
