Alright
so equation is
A(t)=Pe^{rt}
P=initial amount
and t=time
r=rate

given
initial amount is 50
rate is 10%, but decreasing by 10% so -0.1
and time=6

A(6)=50e^{-0.1*6}
A(6)=50e^{-0.6}
A(6)=27.4406

A spherical block of ice melts so that its surface area decreases at a constant rate: ds/dt = - 8 pi cm^2/s. calculate how fast
sveticcg [70]
The rate a which the surface area, S, decreases is
\frac{dS}{dt} =-8 \pi \, cm^{2}/s

The surface area is
S = 4πr²
where r =  the radius at time t.

Therefore
\frac{dS}{dt} = \frac{dS}{dr}  \frac{dr}{dt} =8 \pi r  \frac{dr}{dt} \\\\ -8 \pi  = 8 \pi r  \frac{dr}{dt} \\\\  \frac{dr}{dt} =- \frac{1}{r}

When r = 3 cm, obtain
\frac{dr}{dt}]_{r=3} = - \frac{1}{3} \, cm/s

Answer:  -1/3  cm/s  (or -0.333 cm/s)
